I wrote a blog about how I went about "taming" or at least calming my aggressive chameleons. It may not work for everyone, but it did will mine. And in the 4 weeks the blog has been up I've already gotten one PM saying that they've already seen progress with their cham because of it, so hey, I may not be nuts lol. http://muchadoaboutchameleons.blogspot.com/2012/04/to-handle-or-not-to-handle.html
