One of my favorite projects was a little 30-second AVI I did to learn more about Adobe Premiere. I called it The Fly. By favorite, I mean that I still look at it once in a while and I still laugh. I did the sliding squishy sound myself. Took a mouthful of orange juice and, well, you get the picture.
And yes, I know there have been several movies of the same title. Because no one is probably ever going to see my version, this does not bother me.
