Rob’s laser microscope build

Rob Cruickshank built this sweet laser microscope based (at least partly, I presume) on my recent project. There are more pics in Rob’s Flickr set, including one of the custom screw-fitting he made to hold down the momentary switch on his laser pointer. Rob also reports that water squeezed from an aquarium filter is an excellent source of microfauna-rich samples. [Thanks, Rob!]
