Though its fake I still love it!! I've been bugging my husband to let me get either a chameleon or an iguana for ages now... but he just keeps saying no. (I do get my revenge though, I just say no to a new bike he keeps asking for!!)
I wonder how fast they really change. I think it's a little slower. Still, survival mechanisms have always sort of fascinated me. Ours is intelligence, the ability to write, and being able to use tools which has led to civilization. Without this we would have died being slower and weaker than most predators. So the chameleon is great because it can blend into its environment like those stick bugs you see at the zoo.
