Front-end Theme Switcher Plugin?

Hello!

I really really LOVE the theme switcher that is used on ANidea (https://anidea.com/technology/build-the-anidea-theme-switcher-using-jquery/) I know there is a tutorial to build one from scratch but I am very short on time with this job and wondered if anyone knows of an existing plug-in that already does something similar?

Thanks in advance
