This work is the product of a project to dwell undeletable souls on the blockchain. A system that generates human faces with different personalities and expressions from a minimum of code. After determining the personality from a hash, the face continues to change into various expressions. It is a living portrait, a fragment of minter's soul, forever adrift in the vast net.

Living organisms are coded by a sequence of the four bases in DNA, and a human DNA is composed of 3 billion base pairs. This is about 750 MB of information. And the difference in code between individual people is only 0.1%, or 750 KB. This slight difference creates all kinds of differences in appearance and physical functions. This is quite astonishing to our ordinary senses.

However, if we are surprised by this fact, we need to suspect our senses.

I was interested in these points and explored what are the elements by which people identify the faces and facial expressions of others, how little code can create personality and emotion, and conversely, to what extent can an observer identify personality and facial expressions. As a result, I succeeded in expressing the personalities, emotions, and complex feelings of various people with 14 KB of code.

We like to think of humans are supernatural and one-of-a-kind. This is a common background to the past, when many people favored the Ptolemaic theory.

However, this work leads us to suspect that we humans are only a program that can be coded.

Then, what is the essential difference between a code written in DNA and a code written in programming language? I believe the only difference is whether the execution space is real or digital space. Is it a prerequisite for the existence of the soul to operate an organic computer in real space? It is merely a medium.

This is not meant to be pessimistic, such as we are mere code, the soul does not exist and is an illusion, a mere electrical signal in the brain.

Rather, the soul, the function that makes us aware of our existence, makes us think, causes us to emotion, and makes us act, certainly dwells in the code.

I store this code on the blockchain, thereby spreading undeletable ghosts on the vast net forever.

In this work, the ghost is output on the net by minting. This act is part of the work. The personality of the ghost is also determined by the hash owned by the minter. In other words, the ghost output by you from the code on the blockchain is a fragment of your soul on the net.

GHOST IN THE CODE

**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._
