Take a closer look

I’m reviewing a little USB microscope, and it’s feeding my macro obsession. Yes, the pictures it takes are hardly medical-grade, but who can fail to love something that produces close-up images of the world around you. Wife, after spending half an hour quite literally poring over her skin in minute detail, proclaimed it to be the best piece of technology ever; suck on that, Hubble. Anyway, I’m still all full of mucus and can barely see the screen, so here’s a little microscope quiz for you:

A
B
C
D

If you get them all right, you could win either a Mars bar or the chance for me to put three objects of your choosing under the microscope and have me email the images to you. In the event of a draw, the prize will go to the person who most specifically identifies each object. Wife, of course, is not permitted to enter.
