Nikon 3D mirrorless digital camera?

reader sent me this picture of what appears to be a twin lens 3D mirrorless digital camera – it was taken at the 4th Putrajaya International Hot Air Balloon Fiesta (Malaysia). Reportedly, the camera had a Nikon label on the back. Has anyone seen this camera? Could this be an old film model?

A larger version of the image is available on flickr.

Nikon currently does not offer any 3D cameras, even though they have already released a 3D digital photo frame and Picturetown 3D in Japan. Back in 2008 Nikon co-funded a 3D R&D project in Japan. Could this be a new digital 3D camera from Nikon?

Update: Busted, this is the Cyclopital3D auxiliary lens adapter for Fuji W3 or W1 3D cameras.
