"The Secure Transport of Light" was the title of a talk given as part of Afrofuture at the Milan Design Fair 2013, about fiber optic networks and the politics of light.

To accompany the talk, I built a photophone, a device designed by Alexander Graham Bell for communicating on a beam of light, and an Infrared signalling device, visible only through the lens of iPhone cameras.

A full report of the talk, and the devices, can be read at booktwo.org.
