So, I was “stuck” on a diving boat with no cell or internet for a week.
This gave me time to followup on @Yves_BAZIN s suggestion and look at the Aurora pattern demos from @Jason_Coon
Took me a little while to port them away from SmartMatrix to FastLED::NeoMatrix, but I got most of them to work (well, they all display stuff, but a few have broken display I think).
I kept my 12 favourite ones, and they’ve now been added to my shirt
For everyone else to enjoy, you can find them here:
In _baddisplay, you will find code that I believe is broken, potentially by me. If you can fix it, send patches
In _notmytaste, you will find code that works fine but that I don’t like as much.
Sorry, it’s low res, I’m still on said diving boat, just happen to have cell reception again, but had to downres from 4K to 480p
