This is HypnoCube

The HypnoSquare 8×8 is a LED square with 64 tri-color LEDs arranged in a square lattice, in a nice desk quality case.

HypnoSquare 8×8 hardware features:

• Runs up to 64 three color channel LEDs (for a total of 192 individually addressable LEDs), with 16 color levels per color channel. Thus the HypnoSquare has 4096 colors!
• Runs on PIC18F4620, which has 64K ROM, 3.8K RAM, and runs at 32MHZ (8 MIPS). We have completely filled it!
• Simple usage - plug it in to the wall and it goes!
• Multiple buttons for user selectable control!
• Optional USB port to connect to your computer for user drawing and option selection!
• Hackable - program your own square to do what you want (difficult though!).
• Expandable - general purpose IO pins and a UART exported.
• Controller board is general purpose - it is useful for driving all sorts of LED projects.

HypnoSquare 8×8 software features:

• 60+ basic effects.
• 10+ transition effects.
• Variable speed randomly smoothed along random paths.
• Dynamic palette morphing for smooth color effects.
• Arbitrary symmetry and affine transform mappings performed dynamically.
• User settable visualization speed, frequency, and presence.
• Ability to playback animations from a computer, with an API and sample code to do so over USB!
• Color, timing, symmetry, and transition randomization for creating unique visualizations on the fly.
• 512-bit random cycle seed saved between power-ups almost guarantees never repeating visualization cycle.
• Created with 20,000 lines of C code, and several hundred of assembler.
• Code is fourth complete rewrite, so is polished and very generalized for future expansion.
• Three 8-bit channels of color computed internally, then dithered down to 4096 colors on the HypnoSquare.
• Displays over 6500 image updates a second to modulate the colors.
• Code cross compiles to PIC and Win32 - see the windows simulator page!
• Uses a numerous hand crafted sprites and animations.
• Contains hidden easter eggs!
