Two-Way Water Mill

Clockwise or anti-clockwise - you decide

This illusion started life as the "Wheel of Confusion" on the old illusions page. But this one has a lot more going on of course. Everything may appear to rotate clockwise or anti-clockwise, or travel up or down, or left/right.

Instructions: Follow the red dots, and the whole contraption will work clockwise (the lift travels upwards, the waterfall down, and the wheel rotates clockwise). However, follow the yellow dots, and the reverse is true! (lift travels down etc.). In addition, the yellow rings at the bottom work in a different way. Sometimes they rotate one way, and sometimes the other. See if you can 'spot' both ways.
