to infinity and beyond...

I was playing around with the screen sharing feature of OS X 10.5 yesterday. On my Macbook I shared the screen with my iMac and on my iMac I shared the screen with my Macbook. For some reason, magic no doubt, this is what happened. It was quite cool to watch as the little picture retreated into infinity. Do you think it really is infinity or is there some physical, mechanical, reason why the display couldn't do that?

I know, I know, this is a pathetic post after such a wait. It's the best I can do at the moment. Two children are just draining my little brain until I can't think anymore.
