Saw this on the front page of mtbs3d.com, my favorite 3d stereo website: Later on it provides the link to the website for the attempt: http://www.tetristournament.ca/ Looks like there is no previous record, so a record will be set regardless. $1000 for the first prize, and $500 for second. Not sure if anyone lives near or is willing to travel to Brantford, Ontario, but there you go.
