Areas of loop erased random walk

[darkfrei]

Hi all!

Here is my try to make a program, that makes areas of loop erased random walk.

There is an agent, that goes to the random direction. I it makes a loop, the loop will be filled and that path will be erased.

If you get bored enough your can help me solve my 'animate sprites transiting between isometric tiles' some day.

I can tell that is pretty neat from the way it is.
Played around with the colors a bit, the fading looks nice.
