I have some large (very large) unicorn horns in my free stuff. Didn't quite get them scaled right for Poser. Anyway, someone put them all together in a wierd sort of bryce render and made a really kewl gnarly tree. I thought it was great. If you have amorphium, you can make a ton of gnarley tree trunks. The first version of Amorphium is on ebay from time to time for under 10 bucks.
