Fellow crafty-types should check out sonicfabric.com: making "playable" fabric out of old magnetic tape! Whoah.

You might also want to check out if there is a local "freecycle" or craigslist. It's a great option for keeping items out of landfills, be they tapes, CD cases, or just about anything! Yahoo.com has freecycle groups all over the country, where people can join, post items they'd like to see gone, get items for free, and even request stuff. Craigslist.com has essentially the same thing under their "free" category in many areas. (Heck, if you think someone might actually want that "Color me Badd" tape, you might even be able to sell it on craigslist!) I checked out the CD recycle place Umbra listed in Massachusetts, as we're looking for a bunch of DVD cases at work for storage, but they do only crush up the plastic and metal for recycled material. Something like freecycle could give those cases yet another life before they got crushed.
