I didn&#8217;t set aside a lot of time to work on it, so it became something of a last-minute project. Today I spent most of my day meeting with bioinformatics folk to discuss herberia and taxa and distributed architectures. I may end up working in a CS research group playing with this (or other) stuff. Anyway, by the time I got home, I only had a few hours to start and finish my project. Luckily, I&#8217;ve been toying around with MIDI on my own. So I took a line from J.S. Bach and tried to reconstruct part of his <a href=\"http:\/\/en.wikipedia.org\/wiki\/Crab_canon\">crab canon<\/a>. (This amounts to reversing, compositing, and normalizing a small bit of data.)<br \/>\n<br \/>\n<a href=\"http:\/\/www.gsd.harvard.edu\/users\/jreyes\/theme.html\" target=\"_blank\">Here&#8217;s what I started with.<\/a>\n<\/p>\n<p>\nTwo hours later, <a href=\"http:\/\/www.gsd.harvard.edu\/users\/jreyes\/crab.html\" target=\"_blank\">here&#8217;s what I ended up with<\/a>. True it&#8217;s not precisely a crab canon&#8212;I prefixed a short introduction before the canon starts proper. But if you played from then on backwards, it would sound exactly the same. That&#8217;s right: I one-upped Bach. He thought he was writing a musical palindrome. Unfortunately, he couldn&#8217;t reverse the attack and decay of each note. He needed me to come along and help him out with the minor, technical details. There&#8217;s no shame in that.\n<\/p>\n<p>\nYou can even <a href=\"http:\/\/blogs.law.harvard.edu\/jreyes\/wp-admin\/01%20Crab%20Canon.mp3\">download my project<\/a> in spiffy MP3 format if you like.
