This is my algorithmic love letter to a forefather of mathematical art: **M. C. Escher**.

To commemorate 125 years since his birth, my goal was to honor Escher’s enduring influence by reworking his iconic motifs into a medium that embraces mathematics as much as he did.

I gave it the name **Escherly Seeds** because its meaning is three-fold:

-	_Metaphorical._ This work can be seen as representing the seeds that Escher planted in the minds of the artistic community, and I make several references to his work. Concave and Convex (1955) and Waterfall (1961) were the main inspirations for up to three distinct optical illusions hidden within this algorithm. Expect Escher’s love of polyhedra – a few of which can be seen in Stars (1948) – to make appearances too!

-	_Arboreal._ This metaphor is illustrated as a tree with surrealist botanical components. It starts out, drawn on paper, as a root network from which a stem sprouts, branching into a fully developed crown with leaves, flowers, and/or fruit. Flowers are depicted as enlarged polyhedra with special properties, and fruit are cyclical structures inspired by the iconic Penrose triangle. Fruit can also, on occasion, be ripe with its own seeds, thus completing its life cycle. The pencil-to-3D effect is a reference to Reptiles (1943) and Drawing Hands (1948), except I take the metamorphosis to the present – becoming fully chromatic, dynamic, and interactive. The seed is planted in Escher's world, and blossoms into ours.

-	_Cryptographic._ Generative art is, in a way, the craft of making pseudo-random _art_ generators. Each output is the result of a cascade of calculations caused by one unique numerical seed, and in this case, it just happens to be an “Escherly” seed! For those curious about the details, I tried to avoid excessively obfuscating the code.

The viewer is encouraged to play with the artwork! In an effort to make the tree feel alive, I used an equation called the Kuramoto model which, most notably, mimics the flashing patterns observed in species of synchronous fireflies. Each cube is animated by an internal “clock” which is weakly coupled to its nearest neighbors. Interacting with these clocks will cause them to align, giving you the ability to synchronize or desynchronize certain areas of the tree.

The collection size is set to 327 because March 27 is the date Escher passed away.

Thank you to all who helped me along the way, no matter the weight of your contribution.

Special thanks: Jiahui Cai, Vincent Cohen, Daniel Bothner

Lumina engages in the delicate interplay of curved, organic lines and abstract forms, weaving a surreal narrative filled with rhythm and dynamism. It illustrates dreamy imagery of cosmic phenomena such as electromagnetic waves, magnetic reconnection, and gravitational pull. In its composition, Lumina balances fluid and structured elements, vibrant and muted tones. The artwork’s glitchy and distorted textures, reminiscent of cosmic noise and stellar interference, further enhance its spatial narrative, offering a visual echo of the cosmic phenomena.

Lumina lies in its balanced integration of organic and digital elements. The first layer of the artwork, crafted with p5.js and a fBm shader, forms an organic texture, adding a swirl to give dynamism and generates diverse color palettes; establishing a visual field. This organic layer is then intertwined with a digital layer, where a custom fragment shader introduces subtle distortions and glitches, adding depth, complexity and luminance to the pieces. The inclusion of noise (and its artifacts) and various mathematical functions imbue the collection with a dreamlike ambiance.

**Blind Spots** is a series of abstract intimate portraits that distill human existence into two elements, the hidden essence of consciousness and the tangible shell of personality.

These elements are represented in the form of a glass sculpture. The first element within the sculpture, akin to a black hole, is a shape that defines itself through the surrounding characteristics it draws in. This halo of characteristics, like a beautifully radiant glass cover, symbolizes the constructed personality. Casting light on these black shapes, shielded by the identities they exhibit, the algorithm invites us to question our perceptions of those we encounter. How deeply do we truly know the people in our lives? It challenges us to consider if changing the perspective could alter our perception of them, while also offering the opportunity to simulate such a change with the help of animation. Perhaps the nature of our identities is as varied as the angles from which they are viewed?

Blind Spots serves as a depiction of my mental journey, transforming abstract thought patterns into a solidified artifact in the medium of generative art. The narrative is inspired by the diverse ways in which we perceive each other, a theme born from countless personal encounters. From a technical standpoint, it steps into uncharted territory for me, being the first artwork to emphasize high-resolution printing capabilities while maintaining real-time animation, a central element in my artwork. It is also my first on-chain project, prompting a restructure of the previous workflows.

Visually inspired by *Iittala - Kaleidoscope* exhibition, which displayed a mesmerizing interplay of glass sculptures and light, Blind Spots features a gradient backdrop punctuated by black shapes that undulate under the influence of a transmission shader, mimicking the iridescent shimmer of pearls. The geometry of the glass cover is crafted through the algorithmic movement of two curves revolving around each other. To produce high-resolution images suitable for printing, a bucket rendering technique with overscan was developed.

Articulated through two elements within each portrait, Blind Spots presents a visual metaphor for a human. This duality also echoes our presence on social media — carefully crafted showcases projecting a polished persona while concealing the authentic self. Together, the elements form a unique character from every point of view.

Drawing inspiration from the intricacies of nature and the physics theories that model it, "Fluiroso" (derived from "Fluidos Ruidosos") delves into the mesmerizing depths of Fluid Dynamics. This is achieved by implementing an accelerated solver for the Navier–Stokes partial differential equations.

Initial density and velocity are placed leveraging Perlin noise, and a selection of up to ten random velocity sources are positioned throughout the area. Augmented by other parameters such as boundary conditions and viscosity, the algorithm embarks on a dynamic journey tracing the solver's outputs over time. 

The resulting animation renders a delicate dance of brush strokes where the fluid becomes painter. The culmination is a repertoire of abstract pieces that evoke movement and invite viewers to discern emerging shapes and silhouettes.

Once the animation pauses to spotlight the artwork, viewers can engage with the piece and press 'p' to restart the movement. While many pieces continually evolve, others settle into a graceful equilibrium.

Immaterial is a long form generative series exploring synthetic biology and botany through a combination of algorithms inspired by natural systems, such as recursion, growth, fluidity and fractal-noise. Originally influenced by the underlying structure of fungi gills, the series explores a wide range of formations and life forms, referencing possible futures where digital and organic systems merge. Through an interplay of 3D- and 2D-aesthetics, each iteration of the series generates a unique tapestry of shades and shapes aimed at creating space for interpretation, rather then directly mimicking the natural world.

Although each individual output of the algorithm ends up as an (almost) static composition, the motion leading up to this point is integral to the concept and experience of the artwork. Like in nature, simple rules define how the complexity of organic material unfold from a set of initial conditions. In this series the viewer is exposed to the process of how a seed grows into a fully fledged organism, revealing the underlying rule-based structure of both natural and digital systems.

_Immaterial is best displayed on vertically oriented screens. To ensure optimal performance, please view the artwork in a modern browser (preferably chrome) on a computer with a decent graphics card._

World Flag is a new artwork by John Gerrard featuring 195 national flags rendered in coloured virtual smoke. Each flag is sited in a fictitious future desert generated uniquely using code-based frequencies, shapes, colours, and skies. These data worlds are spatial and solar—viewers can look around the scene by dragging in its window. Dawn breaks and night falls accurately for the locale that each flag represents across day and year.

World Flag imagines a shared but bleak and deeply inequitable future in which ongoing governmental and legislative failures alongside environmental degradation and mismanagement have rendered the state as a ghost, as an apparition of itself. The national flag is reimagined as a performed militaristic sign for a doomed place-based political order.

All 195 World Flags in the series are generated from one 112 KB script stored on-chain. This script uses the WebGL (web graphics language) protocol, a new medium which allows complex visual data worlds to be rendered directly in the web browser. When distributed using the blockchain mechanism and viewed on mobile electronic devices, the work and medium propose a global public art experience—post place, post geography. 

These are spatial worlds - drag on the scene to look around. Press F on a keyboard for full screen, R to slowly rotate the camera. M to hide the mouse pointer. On a phone or touch screen tip the top of world to go full screen. Tip bottom of world to rotate camera.  Tip top again to leave full screen. Tip bottom again to leave rotation. 

Further Notes
The ClimateWatch 2019 greenhouse gas (GHG) emissions index for the 195 member countries of the UN is a key conceptual underpinning of World Flag. The artworks from the project will be released in a predetermined order based on the 195 countries’ respective GHG emissions, from highest to lowest, irrespective of population size.

Gerrard will also produce a single Artist Proof (A/P) World Flag NFT—a composite of all 195 countries represented in the project that will be reserved for institutional acquisition, and it will be minted upon donation.

John Gerrard will dedicate 10 percent of artist’s proceeds from World Flag sales to Hometree, a nonprofit organization that works to address Ireland’s declining biodiversity and the global climate crisis. Through its Wild Atlantic Rainforest Project, Hometree is restoring a temperate rainforest in Ireland, a unique ecosystem.

In 2021, Gerrard became the first artist within Pace Gallery's program to release an NFT with Western Flag (NFT), an artwork derived from his simulation Western Flag (Spindletop, Texas) 2017, which was commissioned for Earth Day 2017 by Channel 4 in the UK. Western Flag (NFT) recently became the first NFT to be acquired by the Los Angeles County Museum of Art.

Gerrard’s Petro National generative NFT series, released in 2022, was the first Web3 project to be produced as part of the multifaceted collaboration between Art Blocks and Pace Verso. In 2023, Petro National #16 (Nigeria) was acquired by the Centre Pompidou in Paris.
