I had my doubts about this; I got an offer from ASPEX corporation to let people get free scanning electron micrographs of just about anything. They make a desktop SEM, and all you have to do is fill out a form and mail it in with your sample of a dead bug or a microchip or bacon, and presto, within a few weeks they'll have it scanned in and the image available on their website.
I asked them if they knew how many readers I have, and they said no problem, they can handle it.
Huh.
Well, you heard them. Scavenge your trash cans, dig into your local sources of vermin and oddments, and send them in. I'm thinking this could be really fun for any school teachers out there — you could have the whole class looking for interesting specimens to zoom in on. You can see their current galleries for ideas.
