How about a sampling of the lists over at McSweeney's, the perfect Friday activity. Here are a bunch that are either science-related, engineering-related, invention-related, or plain unrelated.
I'd be interested in any kind of ranking people have, the bests of the links, that is.
We'll do these in reverse chronological order...
