LED Matrix Sandbox v3

Now tuned around the 64×64 target with a more water-like solver, crisper pixels, and a rotating device view so the whole matrix turns instead of only dragging gravity abstractly.

Matrix preset

Panel price only. Controller, battery, IMU, and enclosure are not included.

Tip: the slider now means rotating the device. The panel itself rotates on screen, and gravity stays “world down.” Left click adds material, right click removes it.
The new water mode is still not a perfect FLIP clone, but it is much closer to an incompressible liquid than the old goo-like particle pile.
