Projects listed here don't deserve separate categories, but I'd like to keep references to them on this site.

nettablet is a small hobby project, that I developed to use a Linux machine with a touchscreen like
Tuxscreen to emulate a Wacom graphics tablet, connected to a serial port of your (Linux) PC. The project consists of two programs: a client, running on the touchscreen system and a server, running on the PC. The server receives touch events from the client and converts them to Wacom protocol packets. The project is old and I didn't develop it too far, but recently someone expressed interest in it, so I decided to mention it on this blog too.
