Burst Through or punch through papers

Does anyone know where I can find such a thing. I think they are .png files and it looks like someone punched a hole in the paper and the edges are curled up in a circular fashion. I purchased them months ago, but my computer has swallowed them up, or hidden them, or dislikes them and, well, I can't find them anymore. I'd be happy to purchase them again, if I could remember where I got them the first time.

So, any help you can offer would be greatfully appreciated.

I wish I could help. What you are describing sure sounds cool! :) But I have no idea.

They are really cool.....you can see them here:

It was much easier to find when I had the right name.....Breakthrough Papers!
