Thanks, Mom!

Also to the E-Commerce Team for trying to break an early version for me during some downtime at work. Your determination to see if it would collapse on itself and observations as to the various features of the game helped a lot. :D

Also to Miles, for trying to see what would happen in a way that only an eight-year-old can. To August, for putting up with me wandering around the house complaining and brainstorming problems. To Andy, who is seasoned in programming languages, for listening to me stumble through really basic concepts and adding guidance when he could.

I'm discovering while writing this that I didn't save the URL that the image background came from. It has been modified slightly from it's original (to be lighter and to tile better), but wherever it is, it did have a reuse license.
