It is possible to method to show dynamic wordpress skin switching according to used input.

For instance.

mywpsite.com/theme/red-colored - shows red-colored skin mywpsite.com/theme/eco-friendly - shows eco-friendly skin mywpsite.com/theme/blue - shows blue skin

Thanks ahead of time

This may be done pretty easily with Kohana (http://www.kohanaphp.com/), that is my suggestion. Other smart you will have to write a controller of your that deliminates the URI and includes the right view.
