Yes, show me your programs and be sure to furnish your source. I'm just casually asking assuming that this post will start to evolve and a battle of egos will take place, leaving the code for extrodinary programs in my lap, (as well as everyone elses). Hmmm....
On a lighter note, of course people program for fun. I suggest checking out
http://www.scene.org for some amazing talent. These people create an amazing show (sight and sound) with amazingly small file sizes. The ones that really impress me are the <64k ones with stunning 3d and sound.
And for the record, the only program language to have fun with is still QBasic
