I spent much of the day writing Mahou, which is the Japanese word for magic, and is now also a Yahoo! Boss Search Mashup Framework and Cappuccino (and Google App Engine, while we're at it) powered image search engine. It's a pretty interesting application, and even the least technical readers might enjoy playing around with it a bit.
A few thoughts and code snippets from further extending Mahou. Written in a rambling style with little purpose or direction. You've been warned.
