On topic: cool. I wonder, would Makerbot adoption force Lego to finally lower their prices a bit (assuming a decade or so for them to give up on trying to stop people from torrenting Legos)?
The cynic in me can't help but point out that we're now looking forward to a future where we don't have flying cars or moon colonies but we can make our own Legos. And then the rest of me replies "Yeah, kinda worth it."
