Some friends of mine used Cthuga rather creatively at a party of ours recently... they basically hooked up a pair of large screen tv's to a video out, mp3ed some cds, and voila! - instant entertainment! Cheap, and way cool! ;D

PS Interesting side note: one of the tv's was placed on a large speaker due to lack of space. This had the effect of warping all the colour on the lower half of the picture without distorting the waveform. People couldn't figure out how we had two different coloured but otherwise identical pictures! :)
