to get multi-monitor desktop mode
Hey, so MilkDrop is a music-visualisation plugin-for Winamp and he has an awesome "desktop mode."
There are some bugs, like icons do not show (despite a lot of effort) on 64 bit systems. What I'm primarily concerned with, however, is getting Desktop-mode to work accross multiple monitors.
It is possible to have fullscreen mode do this, for example.
