25 ft Tall Octopus Flame Organ at the Maker Faire 2014

This mechanical DIY project can hold 200 gallons of propane, and is called "El Pulpo Mecanico". The Maker Faire, a massive annual gathering organized by the magazine Make, is expected to draw some 130,000 attendees in San Mateo, Calif. The first of three flagship Maker events this year, it's a sprawling array of art projects, engineering experiments and geeky toys. Mechanical spectacles like the octopus, n'ee El Pulpo Mecanico, are business as usual. Video courtesy of Patrick Gosch
