A young man I know has taken the initiative and managed to get his community council to equip the local park with a basketball hoop.
These are expensive and so today’s invention is intended to help people play competitive games with only one.
The hoop and its frame would be mounted on a wheeled base, running in a semicircular track, as shown (A-B).
Immediately one team gets possession, the hoop flashes around to the end they are playing towards.
The movement could be powered by an electric motor, but I fancy the idea of two teams of supporters, vying, under an official’s supervision, to move the hoop to let their side score.
