I recently received another toy camera, a Diana F+ copy, with a fisheye lens. The circular vignette within the square format of 120 film is certainly as interesting as any image that shows up within the frame. And I think for me, having grown up in the 1970's, any fisheye image has strange allusions to NASA images and the Apollo flights.
The clear warping of linear perspective is pretty compelling, especially when still contained with the Euclidean circle and square. A bit like peeping out the motel doorviewer to see what that strange sound was.
