Since today (11/11/11) is the last 6 digit binary date this century, I thought we should look at some kinetic binary calculators.
Here's a video showing it in action:
Another video with a few more details regarding its operation:
A quick video showing it in motion:
Andrew Carol has built a couple more complicated mechanical computers out of LEGO. He built one based off the Antikythera mechanism, which was a analog computer for calculating various astronomical dates. Andrew provides more details here.
He also built one based off Charles Babbage's Difference Engine, a design for a mechanical computer from the 1800s that could calculate 7th order polynomials to 31 digits of accuracy. More details on the LEGO version can be seen here.

What do you think of these mechanical computers? Does anyone want to build the Marble Adding Machine? I know I'd love to see someone try!
Have a great weekend and if you create any math-related art, please share with all of us on the corkboard. If you find something cool on the web please share that as well. I hope to share community content in a post on Monday.
