We're pretty sure it isn't practical, but Jorge Cross's amphibious vehicle design for the year 2030 fills us with warm fuzzies with its retro sci-fi feel. The three-wheeler tapers to a single ball at its front, which rotates 90° to reveal a propeller or tire, depending on if you're traveling by land or water. It's graceful chassis design was a study for Cross on the theories of hydrodynamics and how they impact a vehicle's shape.

Jorge Cross is a student at the University of Monterrey in Nuevo León, Mexico. Check out the gallery below for more of his amphibious vehicle.
