Nokia develops phone that knows Morse Code
'Finnish mobile phone maker Nokia is attempting to patent an optical messaging system by equipping handsets with a large light emitting matrix. The backlit display, which can be color or monochrome, generates scrolling or blinking symbols that can be recognised at a distance of up to 4 metres.

According to the firm, the device provides a new communication channel that does not pollute the RF band.'
