El Pulpo Mechanico lights up the night

One of my favourites every year is "El Pulpo". A combination of art and technology melded together, it built knowing that it would be fun to watch as the giant cam spun up through the center moving the tentacles and eyes in and out while fire spewed from the tentacles and head. No hydraulics or computers were used in this contraption. It was built primarily out of recycled and used junk found from a local scrap yard.
