Jumping on the Repurposing Wagon

I've checked out the CD repurposing ideas on Pinterest. Most seem kind of tacky, but what do expect for a "donut disc" that is pretty much a dead giveaway upon first sight?

I'm experimenting with a few ideas to see what I can do.

I showed my husband my yarn-wrapped crochet base when he came home last night.  He asked what I was going to do with it. I had no answer - then realized I just wasted my evening doing the crochet/yarn wrap thing when I could have actually been working on my real crochet project.

My other challenge is to come up with a repurposing for the obsolete Iomega Zip Disks. I'm really stumped on this one.
