one of the two things Blender's any good for (prejudiced? me?..;) is a discombobulator function.
It generates greebles on any object; the trick is how to get it to work right (I created a tutorial for it, but lawsi knows if it's still up or not.) Blenders' free at blender dot org. Now if the interface wasn't so.....(insert depreciating comment here...;)

have ta check the sites above; always looking for a better greeble.

Reminds me of (I'm dating myself...;) a Led Zepplin album cover from waaaay back; I think the original beach is in Scotland or Ireland somewhere....

I wish I'd said that.. The Staircase Wit
