Ecommerce multi-functional plugin

Hello,

I’m not even sure what they would call this and whether or not it’s a plugin, a shopping cart feature, or something that has to be created by a software professional.

But I’m looking for an editor exactly like this site –> http://www.polyvore.com/night_out_on_town/set?id=80784980

where you can create these collages and as you hover over each item with your mouse information on that items pops up and you can click it to go to that product page.

Anyway know of anything like this?

Thanks so much!
