I apologize for using jargon in a public forum. Here is the link to get the filter I mentioned. http://stevesdesktopphotography.com/plugins.htm

I don't think it's what you are looking for, but it might work or you might find something else. These collections are full of fun stuff.

FF Gallery E has a hexagon plugin that might be useful. When I did something like this I put the honeycomb grid on a separate layer and went back and forth with magic wand on additional layers for the cut-and-paste.

Filters Unlimited has a Photo Aging Kit that colorizes, fades, adds dirt and scratches (even coffee stains), and creates old-style photo paper edges.
