Continuing with Atlas experiments... This time, it's Europe Weather map, showing real-time weather conditions across some European cities. It's based on VirtualEarthMap control with custom pushpins. Just hover your mouse over some weather sign and you'll get current weather conditions for that city [in Slovenian language only].
At this point, this is just a sample, so I wouldn't call it a mashup (yet). I'll add new features in the future. Also, loading can be a little slow on slower boxes, so it might take a few seconds for weather signs to show on the map.
The current weather conditions are provided by national Environmental Agency.
