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.

ah thank you. Very nice little project, that might have some practical uses not thought of yet!
