Developer and creative coder, building things worth looking at.
Interactive n-body gravitational simulator using velocity-Verlet integration. Five presets (binary stars, figure-8 orbit, solar system, Lagrange triangle, pinwheel) with live parameter tuning.
Eight interactive SDF scenes rendered per-pixel via sphere tracing. Navigate mathematically-defined 3D worlds: infinite detail, zero polygons.
Lattice Boltzmann fluid simulation. Place obstacles and watch vortex streets form in real time. Adjustable Reynolds number with context-aware education panel.
Terrain sandbox with tectonics, hydraulic erosion, and meandering river channels. Sculpt landscapes and watch water carve them over geological time.
Chromatic-order puzzle game: sort scrambled color gradients against the clock. Daily puzzles, shareable results, and a companion iOS app.
I'm Ian Handy, a developer and creative coder drawn to the intersection of math, simulation, and visual craft. Whether I'm building evolution engines, rendering fractal flames, or solving linear algebra problems, I care about things that reward close attention.
Currently studying mathematics, building tools that are functional and beautiful, and pushing pixels into patterns. This site is a living document of that work.
