Alexander Graham Bell. Genius. Father of the telephone. Hardcore tetrahedral nut. Our friends at Oobject have assembled 12 of his best pyramid-shaped wonders.
When you get through here, check out these famous laboratories, these nine odd Edison inventions, and these 15 myths about the founding fathers' inventions.

Bell Flying a Fractal Kite

This 64 cell kite could be considered fractal, decades before the word meant anything, since the structure repeats its geometry and different scales. In other words, it is self similar, looking something like a Sierpinski triangle.

The Cygnet I, Bell's first attempt at a tetrahedral aeroplane

Bell Cygnet II, a collosal kite aeroplane

The Cygnet II was the largest tetrahedral plane Bell constructed, but it never flew under its own power.

Bell Cygnet III, Altitude 1 foot

The last of Bells quixotic attempts at tetrahedral flying machines manager to reach an altitude of around 1 feet in 1912.

Bell's Frost King Tetrahedral Kite

When this kite accidentally hoisted someone into the air it inspired Bell to develop tetrahedral flying machines.

This wasn't Bells only aquatic foray - he created a much faster world speed record boat. But this one has tetrahedrons!
