My first instinct would be to use an existing Mac OS X screensaver (there is
one that does pretty nice slideshows) for this particular task instead of
writing a new app.  And if you still want to learn something new, look into
the Quartz Composer app installed with developer tools -- it can do some
really impressive stuff, and the programming environment is extremely cool.
If your main focus is fullscreen graphics with OpenGL effects and
manipulations, this seems like the way to go.  Cocoa would only complicate
matters....
