My brother was nice enough to take a hammer to a malfunctioning scanner. While the bits of plastic were destroyed, I was able to scavange the (near unbreakable) glass platen, a stepper motor, and some assorted parts.

I tried cutting the glass for another project, but no luck. This stuff is amazingly tough! It did find a perfect home, on the top of our Mystery Tower:

The Mystery Tower

So, what kind of tower would need a glass top? A very sturdy glass top.
