The odd number indeed served me well in the end. Especially the Conway's Game of Life benefits from this by giving very nice patterns because of the true center line. My alignment is off by up to half a centimeter in some lines by the way. I can still fine-tune quite a few, but it won't be perfect (but I didn't expect 'perfect' anyway smiley-wink)

I'll open-source the code in a few days, when a few bugs are resolved.

So, I decided the first thing to do with my Arduino was to create a LED cube (I love those things) and seemed to underestimate the work (and money) it took. Never soldered a thing in my life and only vaguely remembered electronics from high school. Great thinking. smiley-confuse

However, after some very long days, it seems to have worked out quite nicely. I used 10 TLC5940 chips, multiplexed over 7 planes using the TlcMux library (thanks acleone!) and the ghosting fix provided by denos in this topic.

Here are some demos:
Fireworks - (my favorite)
Conway's Game of Life -
Planes sequential -

Hope you like the show :-)

Why 7x7x7 you ask? I simply ran out of money to buy the extra 169 leds and 2 extra TLC's to upgrade to 8x8x8. Good reason, huh?
