Yeah, okay… I couldn’t think of a good subject!
No… seriously. Sometimes you can download apps for Windows and Linux that
can draw directly onto the desktop. For XWindows you can get things like
Amour (I think that’s what it’s called) and other little things.
My question is whether it is possible to produce such things with SDL, or
whether I would have to program in X to get these results?
Cheers,

You would have to program in X. Actually, that’s not strictly true;
using the SDL_WINDOWID hack I got smpeg to play video on my desktop,
but in general, it’s true.
