The cube MHE-Cube was my first LED art project.
The cube MHE-Cube was my first LED art project. It was a gift from a number of employees at Statistics Austria to new founded company MHE & Partner. The cube form was chosen because that company was working with "OLAP Cubes" which is a form of representing data in a three-dimensional table (sort of...).
Once plugged in, the microcontroller on the board lights the LEDs in various patterns. Also, a 1 GB USB-Stick is included which can be accessed by the PC connected to it. This way the cube can actually store data ;)
The light effects software is available here: avrlighteffects.tar.gz (README included). It works on an AVR microcontroller as small as the ATTiny26 and it's controlled by a simple scripting language. Light effects for up to 8 channels can be designed and previewed on the PC and then flashed onto the microcontroller.
Here's a video of the finished cube:
And here you can see the opened board:
