fisheye?

I've been playing around with some binoculars. Thought I'd try shooting through them as a poor man's zoom. Couldn't get a focused shot that way though. Maybe if I tried the tripod it would be easier but I'm just playing at this stage.
I had more luck reversing the binoculars. Got this false fisheye look.
Not a good shot but an interesting experiment and one I'll file away for further investigation when next I'm bored.
