I was playing with it this afternoon and ended up with something that I thought looked like an octopus's tentacle, so carried on and made an 'eggtopus' cos it's head looks like an egg.
I made the tentacles by extruding a cylinder numerically by 12, then tapering each set of vertices and snapping together the last lot. Then applied the wave tool.
Don't know what use it is but it looks nice.


There's a 'fur' one too that lets you grow grass or hair, but I haven't downloaded that yet, there's a problem with the web page.
