Being the mathematically inclined person that I am I decided the easiest way to do the draw was to print out the comments, number them, and then use my trusty calculator to randomly generate a number between 1 and 24 inclusive (since there were 24 comments). The way this works on a Casio FX 82 is to key in "Ran # x 24 +1", push "=" and ignore the digits after the decimal point. The "+1" is so that the numbers generated go from 1 to 24 and not 0 to 23, in case you were wondering, which you probably weren't, but hey, I don't mind :-)
And the winner is ... drum-roll ... comment #8, Chookyblue from New South Wales, Australia. Conratulations Chookyblue. Let me know your snail mail addy and your prize will be winging its way to you!
Thanks, everyone for participating. I had fun getting all your comments. Let's do this again sometime.
