Oloids
The oloid is a geometric body that was invented by the Swiss inventor, mathematician and artist Paul Schatz. The shape is created when you merge 2 circles at an angle of 90 ° in such a way that the rim of one passes through the axis of the other. The reverse is also the case. 
The oloid is characterized by the tumbling movement with which it, moving over its entire own surface, moves over a flat surface.
