Microscope image of a slice of truffle fruiting body. The dark regions are the spore-bearing tissues and spores.
The petrological microscope I've been working with. The camera is the bit on the top.

2003 electron micrographs of an indian shell bead, taken while I was at Humboldt State University.
(Sadly, I don't have any further notes on the bead or it's origins handy...)

Toilet tissue marked with yellow pen. Blue shows the fluoresence present in the tissue with the yellow ink seemingly sat on top of the fibres.
The scale - which Carol provided via her stage micrometer - is at 10 micron intervals. The spores were max 21 length in water but slightly larger in the neat food dye. As Carol points out - spores tend to be measured in aqueous ammonia - which is nasty stuff - so meaurements of spores will vary somewhat depending what you use. Top left - water. Top right, a discharged spore which ought to be the ones you measure - but the frosted specimens produced very few. Top centre the barely swollen-tipped simple paraphyses. Bottom left, asus and spores in Melzer's - the tip stains blue (not so with Tarzetta). Bottom middle, the ascus "lid". Bottom right, ascus and spores in red food colouring.
In the Picturing to Learn project, Harvard undergraduates were asked to create a freehand drawing to explain to a high school senior how the motions of large and small particles suspended in a fluid are affected by an increase in temperature of the fluid.
