T3 Theme Selection For Every Page

Hi,
First of all, thanks to developer for the great framework.

My question is, how can i create theme color menu for visitors to select and the theme remains for entire browsing.
I have search this forum for a solution and found one suggestion to assign a menu to specific template with theme on it. However, the template only works for that menu only. If we click other menu, it will revert to default theme which were assigned to most of the menu.

Is there any other technique? Any third party extension?

Thanks in advance.
