Comparing those 2 pictures, I'm actually amazed at how different they are. The seat is shaped slightly differently. The Pixar seat has springs and mounting rails, where the other has nothing. The Pixar frame is rounded, the other frame is squared off and looks like it has should pads. The Pixar wheel is spoked. The other has a triangle-like center. So, the similarities? They both have all the basic parts of a unicycle, and they're red, and the frame is slightly oversized.
