We got involved with the RepRap Project, a community focused on making 3-D printers that could make copies of themselves and help create a world without money. We started making prototypes.

I still have the first bottle opener I made on my MakerBot. Things you fabricate are things you care more about. I think there will always be people who go and buy crap at the dollar store. But I think it is cool when people craft things themselves.

My parents had a software company making children's software for the Apple II+, Commodore 64 and Acorn computers. They hired these teenagers to program the software, and these guys were true hackers, trying to get more colors and sound and animation out of those computers.

Learn how a 3D printer works. Get inspired. Make your own stuff. It is a wonderful time to be innovative. Connect things together. If you're into electronics, get an Arduino.

We're on the brink of the next industrial revolution. Instead of buying things, you can make them on a printer. When you have a 3D printer, you can iterate more - what used to take months, now takes hours.

We wanted people to 3-D-print anything, not just more 3-D printers.
