I recently read about three-dimensional displays and ways to visualize data in three dimensions and found what is called LED cubes online. There exist many different versions of LED cubes in a variety of sizes. The most popular size seemed to be 8x8x8 single-color LED cubes (see for example the popular Instructables Cube here). I was so fascinated by the LED cube that I built my own. Check out the photos and videos I took during the construction process. Detailed instructions and hints about building your own cube will follow soon.
