a roulette wheel. The wheel is made of wood and has 38 slots, numbered 0 to 36. The slots are colored red and black, with the 0 slot being green. The wheel is spinning and the ball is in the process of landing in one of the slots. The image is taken from a slightly angled position, so that we can see the ball as it is landing. The background is black, which makes the wheel and the ball stand out.
