(Hey, it is a really cool application and I'm curious!)

It took me about ~30 minutes to write this (I wrote something similar for a different thing oh so long ago).

I apologize for using magic numbers for pixel locations. Also, do not run this if you're not willing to give up the use of your computer for a minute.
