Very beautiful work and great presentation. Via HN
Finally, a huge thanks to my friend Alex who listened to me ramble about marbles for several months every day while walking home from work, gave a ton of helpful input, and lived with the dozens of ball bearings scattered across our apartment.
Yes thanks Alex! :D
