[ANN] New tutorial: Random walks

[TorfusPolymorphus]

I just finished my random walks tutorial, which explains different techniques for random walks. Random walks can be used to create effects like strings, grass, roads, etc. or to place objects randomly.

Comments are very welcome!

Make sure to check out the new tutorials main page, too, which has superseded the old "design ideas" page.

If you want to see a certain tutorial, feel free to post the idea.
