For a minute, I thought the three big things were three blades of grass! :-) You had me fooled! I do really like your grass. I've played around with the fur tool, but only for mustaches, gnarly hair, and eyebrows. I don't think I've even noticed the grass feature!
I'm glad I found this thread! I've been trying to figure out grass forever (I've used digital photos of grass, Photoshopped green noise with bump maps, &c &c usually with mediocre to lame results).
NICE JOB! :-)
