I just realized that I never properly documented any of my DIY projects - wearable flash rig, diffusion panel or light stand. Consider this in place of a "proper" documentation.
these photos were taken with this rig - Nikon D90 on-camera flash driving via CLS 2xSB600 flashes being controlled by TTL. Manual control is also an option. The rig is made of 1/2" schedule 40 PVC pipes and joints. It is a great conversation starter but be careful if you decide to wear it in the club - please be gentle to your neighbors in crowded places.
After this post was published I found an even more grandiose approach to a moveable lighting rig: Human Light Suit. Designed for exactly the same purpose, Eric Schwabel's rig can overpower the Burning Man sun! And the catch-light is nothing short of amazing!
