There was a cartoon I used to see in the early sixties, black and white, probably old even then, maybe 30's or 40's. It had some kind of discordant jazz music in the background, no speaking, and there were these creatures who were essentially an eyeball on top of a vertical metal pole, with a wheel at the bottom. These damn things were, I think, chasing something or someone inside a building. I think there might have been predatory vacuum cleaners in it too.
I would love to be able to identify this and view it again as an adult. It absolutely terrified me.
