Here's a great YouTube vid of pilot and his aluminum Foil twin engine Cri-cri. What a blast it must be to fly that baby. I don't know if the guy is really tall or the cockpit is really that small.

From Wikipedia:

Designed in the early 1970s by a French aeronautical engineer Michel Colomban, the Cri-cri aircraft is the world's smallest twin-engine aircraft. At only 16' wingspan and 12'10" length, it is obviously a single-seater.

The Cri-cri Fan Site has more information.
