Today I only cleaned up and commented my code, wrote some examples and understood how to zoom into a noise plane with the center in the middle (example5).
The white dot in the analyzer window shows you which example is running.
The code with many comments you can find here: https://gist.github.com/anonymous/29388692c2a030cb8738
Questions? Ask!
Do you have any inspiration for me? I am happy to hear it!

This is looking awesome. Much thanks for sharing! Am cleaning up my code to be loop/time demo friendly. Am also playing around with noise and multiple sine waves myself.
Cool, make a showreel and show it to us! 
@Stefan_Petrick Got lots of sine stuff ready, but it will take a while to really understand the variables and demonstrate different effects for fill_noise16. I’m just using a single 1D strand.
As always, great work. What song is that?
Boooo for the dead pixels, did that diode wiring diagram prevent any further LED duds?
Fantastic, as always Stefan!
@Jon_Burroughs It is the album Hu from Orange. That track: https://www.youtube.com/watch?v=R0Pn8uib_z0
A really great live band! Until now the diode did a good job.
@Andrew_Tuline : If I need to understand or at least see what is going on with many variables I use to watch them as a scrolling graphs on the matrix. Before I did that I drawed graphs with processing. How do you get your sine waves out of sync to avoid a periodic pattern? A random step here and there?
@Stefan_Petrick Currently my sine and noise routines are separate and my sines are definitely periodic. What I’m trying to do right now is make my routines highly customizable and to be able to use time based demo loops. Here’s an example with sine, which shows how you can use a few lines of code and get a LOT of different looking displays out of it. See: http://pastebin.com/wUfaZHsF.
Very interesting! Code to discover… Great, thanks for sharing!
Love this. Thanks for sharing!
This is great, thanks for posting
Oh that’s awesome. You’re running on a teensy right?
Not yet. What you see are arround 70 fps on a 16 MHz AVR…
Holyshitawesome. So I might have some hope of getting it running on a 512 pixel matrix on a 32u4, that’d be smashing.
2,5 kB RAM seems to be edgy when using 1,5 kB for the frame buffer, but give it a try!
Heh, been there, done that and got the t-shirt. That’s why it’s a 32u4 and not a 328 
ich find alles supergeil, aber der eq in der ecke ist der brüller! ich plane demnächst einen trip nach berlin zu einem freund (claude/trigger cdv) der mir nachhilfe im projezieren gibt. könnten wir uns evtl. auch einmal treffen? grüessli matthi
Klar, wenn es zeitlich und räumlich passt, gerne! Meine Kontaktdaten findest Du hier: http://www.stefan-petrick.de/wordpress_beta/
