A small collection of simple demo effects for DOS using mode 13h, written to be compiled with Open Watcom 1.9.
With Open Watcom 1.9 installed, just run "wmake" to build all effects.
A simple fire effect with some horizontal offset on the seed lines to make it more interesting.
Classic plasma effect using a sine table and fixed point arithmetic.
Palette rotation wormhole effect. It doesn't look very good right now as the bitmap was converted from a 640x480 BMP to a 320x200 PCX and a lot of artefacts were introduced.
Rotozoom effect, rotating and zooming a texture read from a .PCX-file using a sine table and fixed point arithmetic.
