Interesting, but I doubt these would ever be used by more then a few people. Why we'd want to create a generic standard in a game of creativity, I don't know. And while these kits are nice, they aren't great.
I was thinking of doing a furniture-type of this.
I've tried building computers, instruments, and all sorts of interesting evented furniture that has proper practical use and it never catches on. People can't be bothered / don't want to load someone else's work and stick it in theirs.
