Part II of everyone's favourite 500-LED xmas tree! Thanks to Jane Street. Check out their programs: https://janestreet.com/join-jane-stre...

Check out Ben Sparks’s campaign video on how the GeoGebra file was made!    • Xmas Tree Interactive Voxel Lights - ...  

And here is what you came for, the Harvard github with details on how to send me your effects as a CSV file. https://github.com/GSD6338/XmasTree

In short: each line of the CSV starts with a frame number and then R, G, B values (one 'column' each) for all of the LEDs in sequence. (You can see examples in the Harvard github.) Send them in by 09 January 2022 either directly on the standupmaths GitHub or email to [email protected]

You can get my tree's coordinates in GIFT format as either a CSV:

Or a TXT file in the old format from last year:

Plus I've put my auto-correcting code from this video up on my github (along with the GIFT coordinates). https://github.com/standupmaths/xmast...

Thanks to all of my Patreon supporters who keep my LED habit alive. You too can help support me:   / standupmaths  

CORRECTIONS:
- Yes, I say "squared" twice instead of "cubed". But I was thinking "cubed". You know I was.
- Not actually "within 10%" but actually I was off by 11.8%. Close enough.
- Let me know if you spot anything else wrong!
