These are possibly the most interesting painting to date. The video of their creation contains a detailed description of our experience with several recent crowdsourced paintings, vandalism of them, a hack of our robot communications, and an attempt to log into and steal control of our servers. This attack was actually featured in a TechTimes article that you can find in the press section.

Also, here is a graphics dump of one of the painting's stroke queue. Amazing Stuff.
