I've created a few computer games that you can play in your web browser. Unfortunately, they were written in Java; technology has moved on, and it's now very hard to play Java games in web browsers due to security restrictions, but if you somehow manage to run them, here they are:

AI Pengo	AI Pengo A Java game loosely based on the old arcade game Pengo, with artificially intelligent enemies. From April 1999. Play it here
3d stereogram Pong	3d stereogram Pong A 3d stereogram Pong java applet. You can also use it to paint your own 100% genuine 3d stereograms! From October 2000. Play it here
