You're right Mark Kriegsman ,

You’re right @Mark_Kriegsman , your “Holiday Twinkles” code does look good on a matrix!

Oh, nice one there.

It’s cute how it fades between palettes as a kind of a consequence of how the whole thing works.

Yes! I feel that there are all kinds of lessons here about how to achieve various effects, and that there’s often an easy way and a hard way – and the real challenge is knowing which one you’ve just implemented.

Oooo, that’s nice.

Well-said, Mark.

Here’s what it looks like on ‘The Lightning Tree’, a creation of mine that’s currently residing in our office.

Ooh, is it precomputed?

Not precomputed – algorithmically generated like all these twinkles!

SAUC plz? I’m using the 8-long string i have so far built (fiddly damn things) with a Raspberry Pi connection:GPIO method:DMA using a python library that is compatible with the neopixel code https://github.com/jgarff/rpi_ws281x
so i may try translating if i get a day spare!

Me too I must say matrix is da way to go for these codes, much more interesting and lovely…
