Prime Number Clock

I got past the part about the definition of prime numbers and I was nodding my head knowingly and saying "Yeah, prime numbers. That's tight." Then I got to the second paragraph and kind of confused and sort of cried. Basically, this thing shows only times that are prime numbers and blinks red when it finds a "special" prime like a Sophie Germain Prime. Sophie Germain, I believe, starred in Get Smart.

The clock is right 7661 times a day and costs $849 Canadian. Unfortunately, the sculptor/obessisive who created this can't ship to the US for some reason which screws my Mother's Day gift idea for this year.
