Low-Res EGA Graphics Demo for DOS

I put together a little demo of DOS EGA graphics in the low-resolution 640x200 mode. It's a "playable" game of bouncing balls, where the player controls one ball that can kind of move. Check out the video:

If you want to try it yourself, or check out the source code, here's a ZIP with everything as it was in the video: GFX.zip. Note that you'll have to run the executable in DOSBox or actual DOS, and that the EGAVGA.BGI file included in the ZIP needs to be in the same directory. This file is some kind of Turbo-C++ specific graphics driver... BGI perhaps standing for "Borland Graphics Interface" or similar.
