This is really cool!

I rolled a few times, then decided to have a look at the code but unfortunately, between one request and the next, it's now responding with 503 Over Quota, so I guess it's the old HN hug of death...

Anyway - quick question: I noticed you mentioned using random.org, which is great and everything, but would anyone be able to comment on whether or not the physics simulation introduces biases that might reduce randomness?

Like, what if I always swiped from/to particular points on the screen? Does the size of the window matter? How about different framerates? I'm assuming that the random.org data is used to set up (some of the) initial conditions since I can't check the code right now.

Thanks!
