I met Marcin at SXSW back in 2011 where he talked about this project (and other doodles).  Some more info is here <a href="http:&#x2F;&#x2F;searchengineland.com&#x2F;behind-the-scenes-with-googles-doodlers-68049" rel="nofollow">http:&#x2F;&#x2F;searchengineland.com&#x2F;behind-the-scenes-with-googles-d...</a>.  Also invited him to come speak at Microsoft to share more about his work (some interesting internal debates about a Googler coming to talk at MSFT ;)
