The screen is
a window.
Move your pointer — or your head. The world behind this page rebuilds its perspective from your eye position, every single frame. I make apps that treat every screen as an opening into somewhere else.
On a phone? Tap enable tilt below — the window follows your hands.
Hi — I'm Alex. By day I write industrial software; by night I build spatial apps under Evo Logix Systems. The trick behind everything on this page is called off-axis projection: the device watches where your eyes are and redraws the world so the screen stops being a picture and starts being a pane of glass. Three apps share that one engine.
An aquarium
with no glass.
A living deep-sea tank that starts where your wall ends. Nyx watches your face — lean left and you genuinely see past the kelp. Your room's own lamplight falls into the water.

Roll the sphere
home.
A sentient sphere fell out of the sky near Teotihuacan. Ten dream-worlds of temple mazes, steered by tilting your phone. The maze in this chamber is live — move, and the ball threads the corridors.

It looks
back.
A desk companion that finds your eyes and keeps them — a face, a voice and a memory, living just behind your screen. The one in this chamber is already watching you.

One projection,
three worlds.
EvoCore is the shared engine — one projection trick behind all three apps, in Unity for the phones and ported to WebGL for this page. The diagram floating around you isn't an illustration; it's the live math, and you're the pe in it.
Open the math — Kooima (2008)
Watch it
happen.
Three apps, one engineer, no standups — just me, a compiler and a camera. Every frustum, every failed build, every shipped world gets posted as it lands. Come watch over my shoulder.
