There's a couple mentions of "Fort Stevens", which probably means the annual Recumbent Retreat: http://www.recumbentretreat.org/ . Take a close look at the panoramas and see if you spot them. (I didn't.)
Never heard of them before. If I'm reading it right, they sell plans? Parts, kits? Not sure. The trike looks and sounds like a take-off on the Windcheetah, with bonded tubes and joystick steering. If you find out, be sure to post more info. The web page wasn't very helpful to me; but for an I.T. person I can be a bit dense sometimes.
