It looks like the company sifteo was aquihired and the cubes software wad opensourced but the actual hardware is now scarce. Just reading this article makes me fascinated with the project and as I have a young daughter who would probably benefit from a tactile gaming system like this I wonder how feasible it would be to resume production of the cubes or even hand craft them from components. I didn't see open CAD files on the GitHub repo but I did notice a UK professor has compiled all of the software and games and modded it to work without their central server. I doubt I have the time to mess with this anytime soon but it seems like it would be a awesome project to restart as a maker/hobbyist initiative.
