Convert photographs to ASCII using Ruby

I just created a Ruby script to convert photographs to ASCII. This is just an initial spike of the idea so the quality can definitely be improved. Thoughts and feedback are welcomed. You can view the source code here and read the write up here. Enjoy!

Just letting you guys know that I was able to improve the image quality. It turns out that by deliberately choosing the ASCII map you get huge gains. See the write up here and the code here.
