The difficulty with that is there's no code or instructions to build your own so despite being "more open than open source" you're stuck implementing it from scratch if you want to make your own. Even if you can make the trek out the the current instance you can't take it home because there's still the core interpreter you need to run on a regular system to read the cameras, recognize the feducial marks, run the interpreter, and output that to the projectors that isn't immediately replicable.

I love the project but it's nearly a decade old and still lives in one location or places Bret's directly collaborated with like the biolab. [0]
