I have no idea what Mindchamber is up to, but this is what Tom said in his latest newspost:
MindChamber is planning a Robot Day for June 10th so you have ONE month to prepare. Make a movie, game, work of art or song with a robot theme and submit it on June 10th to be part of that action!
So prepare a robot-tune to submit for this day goddamnit I mean BEEP BOOP BLOOP CLANK
I would guess that everyone's supposed to submit their robot-stuff on the given date, not sooner or later...
