My 32 x 18 panel project was a great success. The hardware worked for the whole night of the party, nothing caught fire, the software didn’t crash and guests were suitably wowed. It was always my intention to release the code, so here 'tis, for your forking enjoyment:

Pull requests, additions of new effects and snark about the quality of my C++ are all welcomed. The intention is for this to be an ongoing codebase, used for the existing panel, my 10 x 15 pixel gauntlet, and the jacket I’m still intending to make for the Burn this year. If it helps others as an executable library of 2D effects for FastLED that’s awesome too.
