Two summers ago I attempted to gather some artifacts from those electronic-music projects — including photographs, documents, scores, memories, and over 4 hours of virtually unlistenable "music" ripped from reel-to-reel and casette tapes — and put them on a web page. At the time, I thought it would be fun to code a bunch of Silverlight 2 utilities to help with the presentation of this material, and I guess I got hung up on the code and never finished getting the page in shape.

Recently I decided to forget about the Silverlight utilities and do the whole web page in straight HTML 4. And so I did and here it is:
