basic concepts

i like to program a little man that is walking around on my screen. Some questions about this:
What fileformat should i use? What fileformats are available? And how do i load it? (some C sourcecode would be nice ) How can i perform the animation of the steps?
(the only idea i have is to store every motion in a displaylist - would you do it that way ?)
Is there a demo available that loads a “sprite” and let it walk around?
Thx in advance for any hints.

Hi !
Some Weeks ago there was an application in the OpenGL Contest (link on It was called “AstroMan” this app shows a little man walking across the window… Maybe you can use something …
