Just got an idea for a new great feature - overlay support. I got it after downloading the latest version of WinAMP (2.74) - the AVS vis library (which is included in WinAMP installation) has this feature and it makes it possible to render the effect directly on the windows desktop (and even antialiased in hardware) - You just have to set the color value (RGB) that will be replaced with the effect. Would it be possible to render the tank in the same way?
