That's really neat! I have all 1536 LEDs in a single string and that definitely is a limiter in terms of framerate but the resolution is so coarse that this hasn't been a problem (so far). But this driver takes it to a completely different level. Unfortunately the Pi Pico (which I would have liked to use) only does 3 A/D channels so that would have ruled out two player games with full x/y control. Fixing that and some other issues would require much more hardware work and I want it to be so simple that even a novice (motivated 12 year old) has a chance of putting it all together.
