We keep a few CDs handy for Jesse bird. He loves his reflection, and that's close enough for him. We got him off the porch roof with an old AOL CD once.

There's an idea - if you have birds flying into a window, you could hang a few CDs to scare them off. It would probably work in the vegetable garden or fruit trees too.

For old cell phones, there are places that take them for senior citizens and program them so they can use them to call 911 for free (they only get them for emergency). And other places use them for domestic violence shelters.

I always drop my old eye glasses off at the post office, where they fix them up for 3rd world countries.
