I just added a few programs I was working on to my web page, http://www.geocities.com/SiliconValley/Bay/2267 One is the beginnings of a Wolfenstein type game and the other is a sine wave graphics demo. They're pretty neat! Check it out and let me know what you think. Oh, and don't forget to download the TrigLib file. It's different from the one at ticalc.org. -Ed
