Holography – the science and practice of making holograms. Typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics.

Harvest a focus lens from a laser pointer, and attach it to the phone’s camera with some wire. The lens will magnify images to make a DIY microscope (full instructions here).

stick a few pieces of clear tape over the flash, and color them with blue and purple Sharpie markers. This filter blocks out most visible light and leaves only the ultraviolet spectrum, turning the phone’s flashlight function into a blacklight (full instructions here).
