Here are a couple of images below I received from Mariano in Argentina. He calls his vehicle the Zome-mobile. The name is derived from the shape.
It was built with polyethylene tubing and joined together with bolts, nuts and washers. It is a simple structure and fast to assemble, very economical and durable, and only requires 20 pipes and 2 rings, one at the top and one big one at the base.
