It's a very cool/fun project and definitely not a cat video. I do believe that it's relatively "shallowly interesting" and I haven't read any comments yet that would indicate to me otherwise. I take the 550+ up-votes it's gotten as a sign that the value (for me at least) of the hacker news filter is slowly degrading.

Sincere answer: I look and this and think: how did they do that? Do I know how to do that? Could I do parts of it "better"? Knowing this is possible, are there cooler things I could do with it?

If you're willing to think about it for a little while, there's much beyond shallow interest.
