I don't have actual "movies", but I do have plenty of animations dating back to 2002. Since I don't have a working BMP to GIF batch converter, I've pretty much stopped making them. For full details about them and some additional ones,
go here,
here (section 5.2), and mainly
here.
These, however, are my most prized animations I've done:
The rocket jump out stunt - I jump out of a rocket from 550 mph, land, then stop.
Balloon sky diving - my most complex animation of all and done entirely in MSPaint (caution: 800KB file size).
Thunder14 spell effects - One of my favorite spells used in my mind game.
Holy6 spell effects - my best done spell effect (note: double-zipped AVI - extract it twice to view (no codec required as zipping it with Winzip gave a much smaller file size than any codec has done)).
Without a working BMP to GIF batch converter, I've practically stopped making animations. Working as in the colors are kept exactly as they were in the original BMPs (and not altered as all of them have so far). It's not the 256-color limitation, a single frame rarely gets any more than 30 colors, or 50 for the whole animation, far below the limit.
In case you're wondering, I make the animations frame by frame. I use two main tools. One is the graphics edittor to make the frames with, and the other is Excel for planning and doing the calculations to create realistic motion. As to how I make them, I've explained it in great detail
here. Caution: This document is at least 2 years old and seriously needs to be updated. It's still fairly accurate though.
