This was something that came to me while at work today. Basically, there would be a new command with parameters that does a screen capture like alt+2 but it keeps it in memory. Some of the parameters that could be used with it could capture just the level, the level with NPCs and showimgs on layers 1-3, and capturing the entire screen. The buffered image could be accessed by #p like those sent by a triggeraction.
For playerworlds that are of a modern theme this could be used in conjunction with showimg to make something of a video display for a camera security system (you'd want to do changeimgzoom with a factor less than 0.9). For other things it could be used for effects similar to the script Kaimetsu did for my Doragon Koden logo for those that have seen it. There would also, then, be the potential to somehow send the buffered image to a webpage where you could check out the game in a webcam-like view; sometimes a still picture is not enough
