GL_ARB_texture_env_crossbar or GL_NV_texture_env_combine4
This is a demo of perpixel shotlights. Two flashlights are flying around lighting the bumpy walls. Looks pretty cool
The effect requires four texture units, a bumpmap, vectorfield, spotlight texture, and a small 2 texel texture to remove the backprojection. (With fragment shaders the last texture shouldn't be neccesary)
It should run on Radeon 8500, Parhelia and GF3/4.
Source is included as usual.
