most ppl have enough difficulty understanding time varing matrices, adding a 3rd spacial dimension and expecting them to comprehend planar math is a tall ask. ???
I would love one on my coffee table. 8)
I saw a massive one of these in China at the led show.. Theres a company that makes the stuff, and they had a cube that was about 3 x 2 x 3 meters.. It was ok, but i have to say, i wasn't super taken back by it.
I think this is something that does not scale well. On a desk as an RGB 8*8 or 10*10 item in a perspex box I'd be impressed and would want one. Make it a couple of meters per side and I think it would just look, well, odd
I once found some sites that had software and instructions for building one and it shouldnt be too hard to locate through Google. One site even had the software so you could design your sequence and program it to the onboard microcontroller. I never saved the site.
Soldering of the unit was realtively simple, you soldered lines of LEDs first (ie the vertical columns and then you combined the vertical columns into sheets and then sheets into the cube. Wiring was a nightmare due to the sheer number of connections needed. Coding would be equally tricky to make patterns and display them smoothly.
