Wow, very random! Rating 10/10.

I made some very interesting and unusual patterns (I couldn't call them "terrains" because they were completely convoluted and hacked up, not unlike a Jackson Pollock painting) by juggling the input parameters with a wide range of senseless values. That was more fun than making terrains!

I like it!

Thanks guys.

I just messed aroud with the _nSmooth thing and added a zero, then clicked five times, and got some very realistic hills.

I also found that the results are very good for mountain bikes.

Suggestion for s_noonan -- Add user controls that will facilitate changing input parameters without having to go through the Script Menu. You could also set min/max range for each parameter. This would make your excellent scene even better!
