- Twixi, a new wiki written in Scheme which should eventually have all the features I wish MediaWiki had.
- Display Scheme, something like NeWS but using Scheme as the language rather than Postscript, and incorporating "metawidgets"
- NetteBook, a web-based PIM (I still use it but it's incomplete and a bit obsolete these days)
- Caller ID broadcast system with server and several clients
- gcode2eps converts 2D CNC g-code files to EPS for previewing
