Bwahahahaha – I know what it is, but I can’t tell you. But you can now play a text adventure game, created by Andrew Plotkin, which will give you hints. Remember Adventure?

You really shouldn’t have wandered away from your tour guide. The gleam of glass in a deserted room caught your eye for just a moment… but with that mob of chattering tourists out of sight, the MakerBot facility doesn’t seem quite as friendly as it did a moment ago.

Servos hiss behind you — but that’s not the guidebot’s cheery mask looming out of the shadows. It’s a security bot! You’re in trouble now. You duck into the laboratory. Or is it a showroom? Test chamber? You pull the door shut; hopefully you can hide out until the robot has passed.

No maze of twisty little passages here. Just a big scary security robot. I just played it for a while – it’s awesomely fun. I expect Seth Levine and Paul Kedrosky will get sucked in this afternoon and it’ll cause Paul to need to buy a MakerBot to print out the pieces in game.

I’ll see you at CES if you are going to be there. And keep your eyes on the MakerBot site for some cool new things.
