I made SandPond, a 3D voxel engine, and a spatial programming language for creating elements in its simulation. I documented my progress in a series of videos called the SandPond Saga. The engine is now complete, but the saga continues.

CellPond, 2021

A spiral made in a tadi web tool.

I discovered the theoretical Tadi Web, an extreme approach to computing that I now use in my personal projects.

Make Real, 2023

I set up Torn Leaf, an experimental online gallery. Its first exhibition is opening in January 2026.

Call for submissions

Logiverse, 2024

Loggy, the Logiverse mascot.

As part of my explorations into the Tadi Web, I kicked off the Logiverse, an experimental distributed social network.
