In Web wizards weave their magic, Bruce Tognazzini discusses similarities between conjuring and web design.
As a magician, and web slinger, I find the article to be amusing. I won't argue with it, but I think Tog should expand his thesis to include computers in general. One similarity he missed is that computer users, like spectators at a magic show, will often create elaborate and misinformed "explanations" for the behavior their witnessing.
