Pix of unknown rotary at Oshkosh yesterday.  You folks that are
there, any details on it?

If it did  not run it could be phony :)
Find a bunch of existing castings and  cobble them up
to look like an engine.

Experimental  aviation is the happy hunting ground of charlatans
and scam artist.  Are they selling stock yet? :)

I was there yesterday, for one day only.  I saw this  exhibit [in the
Rockwell hangar?...same hangar as DAR Corporation  booth]
and I spent some time chatting with them.  They are from  New
Zealand, and are looking for investors [see Paul's very  wise
remarks, below!]  This is NOT a working engine, in fact, the  crank
does not even turn.  It's internal design can be seen on  their
website

...check out their  'home' page, under 'technology' video.  It uses
a swash plate, and  axial sinusoidal movement of pistons moving
that plate, which turns the  shaft.

Similar to or copy of the Almen aircraft engine from WWII.
