I wish I had anything meaningful to add to this eBay auction that's currently underway, but I think I'll just let the description speak for itself:
Built on a 1991, 28-foot-long International boom truck, the Scorpion is a 55 feet long, 22-45 feet wide, 39-45 feet tall exact replica of a female emperor scorpion named Fluffy. The Scorpion boasts a computer controlled 7 gun flame thrower off the tail, 21 hydraulic points which make the arms, legs, and claws all move in a sinister spider manner including hydraulics which make the entire truck lift off the ground to produce the most eerie of effects. The project is "skinned"- as in made to look like an exact replica of a female emperor Scorpion with artistically placed and sculpted metal sheathing. The final touches are a steam punk look with rivets, textured fabrics and a patterned, oozy and highly mesmerizing multi- color light show.
This ridiculous machine has done duty at Burning Man (where else?) for the past five years, but apparently, it's time for the current owners to move on. Please note that the scorpion truck is not street-legal, so you'll have to find some other way to get it to and from the Playa.
Here is a video — a very Burning Man video, may I add — where you can get a taste of the truck's capabilities:
Bidding is currently at $50,000. Good luck.
