Plugin to allow users to change schemes?

Hi all,

I’m wondering if there is a plugin out there that will allow a user to come on to my site and choose a “style” they want to use when on my site. Like if I have a theme and make 3 different styles (with everything the same except for like the header picture and colors on the page) and want a user to be able to choose any of the 3 to see when he/she comes on. I did a search but didn’t find anything but wasn’t exactly sure what I was looking for either.

TIA!
