Steer a (virtual) radio telescope around the sky.  Listen to whistlers from Jupiter, the repetitive pock-pock-pock from a pulsar, the loud noise from the sun and the constant faint hiss from the CMB no matter where the receiver is pointed.

Many years ago I observed the sun with a small dish controlled from the visitor centre at Jodrell Bank.
