Here are videos of this years Apogaea portal with 1200 APA102 LEDs instead of last years 512 WS2812s. I used 1” ping pong balls rather than the standard size. Ended up using a Pico to run this as the v3 pixel blaze I used last year was finicky and unstable and it wouldn’t update its firmware. The Pico did a good job, better than I thought it would and no issues.
