[Caml-list] x-windows screensaver in OCaml

[Caml-list] x-windows screensaver in OCaml

[Brock]

So one of these days I'd like to write a screensaver in OCaml for
xscreensaver, which means drawing on X's root window. Any suggestions
for a super-simple way to do this? The primitives in the built-in
Graphics module are plenty for my needs, I just don't know how make it
appear on the root window.

Thanks,
--Brock

(I'd suggest beginning with reading the source to some existing
xscreensaver hacks*.)

* hacks = xscreensaver term for the individual screensavers

I'd suggest trying to replace the functionality of one of the existing OpenGL 
screensavers with your own code.

Cheers,
Jon.

You know of some OpenGL screensavers in OCaml by chance?

So far it looks like I'm going to have to do some of my own C bindings.

I think there's a library for using the Xlib API available that might work
for this.
