A multimedia NFT that generates a unique beat and sandbox. Then you start beats and sand grains will vibrate & change colors according to real sound waves.

You can pause, restart, increase number of sand grains up to 4M and resolution up to 4K.

This is n°2 in my diptych of generators of sand-like particle systems driven by beat waves.
N°1 in diptych is focused on early-stopped systems producing cool static visuals and mintable there -> https://www.fxhash.xyz/generative/slug/sandbeats-diptych-1

WARNING: Webgl/GPU compliant, CPU compliant but might lag with 1M/4M particles, runs on Mobile but lags.

Controls:
- H: hide/show help.
- Dbl-Click - Space: start/pause animation for snapshots.
- S - Z/W: particles more/less (256^2, 512^2, 1024^2, 2048^2).
- Q/A - D: resolution down/up (720p, 1080p, 2K, 4K, 8K).
- R: restart animation from scratch.
- I: hide/show info panel. Click for panels (info, FPS).
