The ThreeRing Web Mapping project adds a dot to a blank canvas showing your geographic location (or that of your ISP, as best it can guess based on your IP address). They've also got a code snippet to put on your own site that automagically adds your visitors to the map. The US is already clearly defined, Europe is getting there, and Oceania is coming into view. (They've also got one of them Tag-Board thingies, which is painful to read for any length of time.)
