Optical illusion · 模型 242186
This design can be deceptive to the human visual perception. When a ball is dropped at either of the two sides, it appears to be climbing up the frame and falling through the hole. But when the design is looked from a different angle, the reality is exposed, where the ball is actually falling down the path.
