Here is a rather cool demonstration of receiving weather satellite images with a low cost USB dongle.

There are several American NOAA weather satellites in a polar orbit around Earth, each of which will pass the same point below every 12 hours or so. The satellites transmit pictures via FM radio at 137MHz. Using a DAB/FM/Freeview dongle, you can receive this signal on a computer running software-defined radio (SDR) software, and then decode it into a picture.

The receiver in this case is a Nooelec R820T USB Dongle, and several other neat SDR applications are also possible with this hardware.
