The image shows an old Olympus T32 flash triggered by the Nikon V1 using my own adapter. The adapter is capable of triggering any radio trigger or any low trigger voltage flash through the shoe or the X-sync contact. This is a unique adapter, not yet made by anyone else. It is not yet commercially available but will be soon.
This image is taken using a mirror in front of the camera. The image was then flipped around to get rid of the mirror effects.
Updated information:
The adapter is now available. Read about the details here:
