Scott Kirkpatrick makes reference in his Leica M8 post to the Leica S1 and the unicorn tapestries. Here's where you can find the utterly charming story of the Chudnovsky Mathematician (two brothers who insist they are one mathematician occupying two distinct bodies), the computer called It built in part with supplies from Home Depot, and the digital imaging of the tapestries. It's a long article, so perhaps you'll have to wait until you have time, but it's fascinating—not to be missed.
