GL_ARB_texture_env_combine or GL_EXT_texture_env_combine
GL_ARB_texture_env_crossbar or GL_NV_texture_env_combine4
A cool little Winamp plugin. It uses dot3 bumpmapping to create a quite nice effect while moving to the music.
It supports fullscreen mode, selectable bumpmap and number of lights and other cool stuff
It should work with all cards on the market, but bumpmapping will of course only be enabled for cards supporting the recommended OpenGL extensions below.
