Cool gmaps // twitter mashup

Walterra has hacked a cool mash up with twitter "weather data" for select Austrian cities and google maps to present a twitter weather map for Austria.

Most probably technically not really challenging ("Done in three hours" in his own words), but the idea (to get the data from twitter) is just great.

This is just a simple example to illustrate the hidden power and possible emergence that lies within social media, presence services and livestreams.
This is a quick hack inspired by metaroll.de. Using summize I fetch messages from twitter which contain words about the weather in Austria's federal capitals. A simple algorithm measures what people are talking about and renders a KML file which gets displayed above

Thanks to phreak20 for the hint.
