Time

For those of you that like to think, I would suggest reading the Time Machine by H. G. Wells. I haven't gotten very far yet, but Wells has an interesting outlook on the fourth demension: time. He tells how we can manipulate it just like we manipulate other objects. Its quite interesting really.

It would also let me see the new "Lunch Makers smiley face" again. Now that's an interesting subject. See Andrew for details.
