no ones remade the Chameleon demo within professional, however i've rebuilt the Dophlin Vertex Shader demo from DirectX ... however will only work on GeForce 3 Ti or GeForce 4 Ti cards, which means its very limited right now.
If you wish to program some good shader effects i'd suggest going to
nVidia Developers site
they have a shader assembly + FVF format converter, plus they're very helpful in the forums.
You can attach any shader that can be developed within Shader Assembly by converting.
