I imagined a red dodgeball on a small brown table. The person was just a thick stick figure and when the ball fell it bounced.
The color and shape I didn't actively choose, they cam be different, but I guess my brain has defaults.
The ball falling and bouncing, however, I had to actively think about, the same way I have to think about texture. I don't have to think about where the ball would stop, or how much it would bounce tho.
Do you have feet and a camera?
