Drill of the Future

I downloaded drill design software yesterday from Java 3D. It's very nice and intricate. I can see how writing is still going to take a long thought out amount of time, but it also saves a crazy amount going back and redrawing on new paper. There are some great features to rotate, stretch, shrink, etc... the written drill. This saves tons of time redrawing the same shape only in different dimensions. The only issue is I can't save b/c I have a demo. I downloaded some software that records the sounds coming out of my computer as a wav or mp3, is there software that records what's going on my computer screen as a video file? If so, where do I find it?! That would be cool. I want to start sharing this stuff with people, but can't b/c I can't save or send these files with the demo and the software is $650.00 USD!!!! No way Jose, not just to fiddle around with. Any help duders?

Today during dinner, Torry told us all how he once glued his foot to a house boat in attempts to keep a cut on his toe from bleeding out. I almost choked on my food. He said it around everyone that had heard the story but me, so it was really quiet until I finally got the food down and busted out with laughter. Oh, roommates are so much fun!
