Laser Microscope

An interesting impromptu project: a laser pointer directed through a drop of water projects a large magnified image on the wall.

Teravolt.org - Laser Microscope.

This reminded me of the setup that Gabor described decades ago for inline digital holography. I might have to give this a try sometime.
