PolskiCrystal Lab (2D)
2D companion to Crystal Lab: a top-down crystal lattice whose pillars rise and fall from two overlapping wave fields, with pointer-injected ripples and a live glow readout.
This 2D companion drives the same two overlapping wave fields as the 3D Crystal Lab through a flat, top-down lattice view: each cell's height comes from a radial wave plus a diagonal pulse wave, rendered with an isometric offset and a hue that shifts with the local glow. Moving the pointer over the grid adds a decaying ripple at that point, and the Wave, Pulse, Glow and Grid density sliders let you retune the interference pattern in real time.
Canvas 2D crystal lattice driven by h = base + sin(wave term) + cos(pulse term), with a pointer-distance ripple term and an HSL color mapping tied to local height (glow).

Each cell's screen position is offset by its own current height, so taller pillars are drawn slightly higher and later (painter's-algorithm depth sort), giving a pseudo-3D relief without WebGL.
Wave scales the speed of a radial wave measured from the lattice center; Pulse scales the speed of a diagonal wave measured along the grid's x−z axis. Together they set the interference pattern you see moving across the surface.
Yes — the same height formula (base height, radial wave, diagonal pulse wave, pointer ripple) drives both versions; only the rendering differs, from an instanced 3D mesh to a flat isometric canvas grid.
