Packing Peanuts

I love playing with styrofoam packing peanuts. They come in interesting shapes, styles, colors, and materials. I've seen lots of pink ones that look like infinity symbols; stiffer white ones that curl back two directions and look like an S when on their side; and the ones that look like unflavored cheese puffs. I wonder if anyone has ever started a collection of the various peanuts available? If you know of any photos of a packing peanut collection, please let me know!
