This radio/art piece by Simon Hasan is a beautiful and efficient little doodad. Volume is controlled by turning the speaker, and frequency is selected by rotating the antenna. Not so great if you get the best 90.3 reception at the 106.1 orientation, but hey. It’s art. Quit being such a nag!
It’s too bad there is only one of these, and it’s too bad I never listen to the radio.
