This is an attempt to convert the javascript ray casting example found here:

At the moment it is a very direct translation from the javascript, but current results are somewhat... uninspiring.
I maintain about 8 frames per second. I'm hoping to find some way to combat this.
Edit:
The frame rate has been brought up to about 20 fps through various simplifications and changes.
Still not amazing, but much better.
