What Do You Do With Your Obsolete Technology?

The advancement of technology comes with a downside: What should we do with all of yesterday's gear?

For some things (the ones that still work fairly well) the answer is simple: You pass it along to someone else. But with the old tech that no one uses (8-tracks, for instance), the answer is not as clear.

Do you turn it into an art project? Hold on to it while it gathers dust in your basement? Attempt to recycle it? Or do you simply throw it away? Tell us what you do with your obsolete technology—and any creative projects you've come up with to repurpose it—in the comments now.
