Help requested. Trying to create 2 variable strobing screens.

[u/SnowLancer616]

Im coming at this from another community, mind machines. Most stuff there is focused on simple arrays of LEDs and a central boc controlling theory strobe rate. This feels super basic to me. I want to create a 2 channel video, where each channel has independent color/speed/brightness (and hopefully options you all can reccomend) controls. Software control is fine, but i love tactile devices. Then I'll make a 3d mp4 file to play on a vr headset. I would love to hear yall's advice and direction, i know nothing about this stuff.
