Here are a few projects I've worked on lately:

Pretty Pictures
Lots of Colored Pencils - I wrote the map renderer for Google Maps
Seashells - rendering thin film effects (a bigger image is available here)
PN Tesellation - Cutting up little triangles
Fun with Eigenfaces - Playing around with correcting affine transformations in facial recognition data
XMMS Terrain - A simple OpenGL plugin for XMMS

Pushin' Bits Around
Viper - I implemented XQuery constructors and XML traversal for DB2 Viper
WebDAV Tickets - Flexible authorization for WebDAV (incorporated into Xythos WFS)
TRAPP - Tradeoff in Replication Precision and Performance
STREAM - There's an acronym in there somewhere, I think (and some publications)

Random other stuff
