I tried remote accessing my PowerBook using the MacBook Pro:

powerbookremote

The screen is not as fluid on the MacBook Pro but I saw the screen on the PowerBook moves on-demand as if I was operating from a KVM extension instead. Well, without the V. KM.

Then, I remotely view my own MacBook Pro from that PowerBook. I view something that views myself. Sounds familiar? The result is this:
