The photos in these series were taken with camera lenses I build out of PVC, cardboard, various kinds of tape, military surplus lenses, obsolete digital cameras, prisms, dichroic filters, projectors, microscopes, binoculars, photo enlargers, old cameras and camera lenses, and anything else I can find that reflects and refracts light in interesting ways.  Below are a few photos of the hundreds of different lenses I have made.
