Here are some shots of the TV screen on the treadmill at my gym.

What does it mean? Is it random? Is it a self-critique about the difficulty of what meaning can be derived from images and sound out of a treadmill screen, when the gym is a noisy place and my concentration should be on things like form, breathing, and effort? Were the screens responding to my workout? Is this a new form of participatory video art? Participatory found art?
