The Thorny Devil is cool! They have similar characteristics to the chameleon. They have the ability to enhance their color and have the rocking and swaying action.
They are found exclusively in Australia and consume hundreds of ants a day....still want one??
You could get a Horned Lizard which is closely related and look similar and are found here....but they mainly eat ants as well and I haven't met many cham owners that like ants
If you could get one, it would be impossible to keep alive in captivity.
Like their North American equivalent (the horned lizard) they eat ants ... lots and lots of ants.
You think it's a pain to keep crickets around?
