I checked the stats of some of my YouTube videos today. I got to the Domino Printer and found that the views had exploded from about 300 in about 2 months to nearly 4,000 in the last day or two. Then I found out why. Someone has posted this video and it went viral. The vast majority of my views were from the "Related Video" link. Still, I will take nearly 4,000 hits.
I have messed around with building a bot that sets up dominoes, but this guy takes the cake. It's a dumb machine that works perfectly. I have a feeling that people will take this idea and add some steering and some domino storage and make some really cool stuff (please do!)
