normal view of the world around me:








Cropped:




The timing band (with all the dots) is an almost barely useful tool.
The speed at which the different dots rotate indicates the relative rotation speed of the plate.
The row of large dots is not moving indicated that the plate is moving at the exact selected speed.
If the top row weren't moving, it would be moving aboit 6.6% faster than the selected speed.
Its only real use is to slow the rotation of the plate that it rests on.
