Would using a beamer, a laptop and WinAMP or Windows Media Player visualizations not work?
For WinAMP there are even some plug-ins that specialize on visualizations, allowing a "visual DJ" to actually have full control over how the different visualizations are used and you download a shitload of them etc.
