I use Trillian as an instant messanger tool because it connects to both AIM and MSN Messanger services.  One of the neatest features of the new Trillian tool is to identify some words in the IM conversation and look them up in Wikipedia (my favorite starting point for random facts).  At least, that's what it says it's doing, but I frequently can't find the definitions Trillian finds when I go looking myself.  Anyway, I was mentioning Keith (Rome) in a conversation with someone and Trillian underlined his name as having a Wikipedia entry.  Curious, I looked at the list - mostly famous people with Keith as the family name.  But it told me to see also Keith numbers.

Man, I love math.  I am terrible at understanding and solving math problems, but the more I learn about it, the more I like about it.  This page just set off the Geek Alarm - big time.  I love this stuff!

FYI - a Keith number is a number who's digits make up a Fibonacci sequence including itself.  For example, 197 is a Keith number:

197: 1, 9, 7, , , , ,
