From the dawn of my time working with things related to graphics. Here I think about 1981 on the ZX-81, later on the TI-99/4A and Acorn BBC Computer. From that time I have loved icons which illustrate something on a small space. Once working on the Archimedes (Acorn RISC computer) I remember a friend of mine got a task where he had to create I think that it was 4 icons for Ericsson – the size was 32 x 32 pixels and only some 64 (or was it 32) colors were available! He worked hard for many hours and actually produced 4 icons which illustrated for instance “Water department”! 
Cool!
Today we are spoiled with great icons! Let me link you up with an article with great links to free icons: Icons For Your Desktop and Icons For Your Web Designs. And a taster – I have downloaded some of the Icons:
When I try to create Icons I use Xara Xtreme Pro (open source version for Linux: http://www.xaraxtreme.org/) – a vector based program – which many great icon designers also use. http://iconka.com/ is a place to see examples of that. Here is a teaser:
Xara Xtreme has by the way arrived in a version 5 here in the beginning of june 2009!

The long range is high frequency and the short range is low frequency.
Soon after the home invasion of popularity they evolved into a favorite kid’s toy for children to communicate in the seventies. Walkie talkie radios can even work in severe storms as the signals are very strong and the speaker of these radios is very loud and clear.
