Visualisation of wind movement from Helsinki weather sensor data.
About two hours of recorded time is shown every second.
Smaller line in the top right shows a line that travels in the direction of the recorded wind movement.
So, if the wind blows south, the line goes down, if it blows west, it goes left, etc..
The larger line is a zoomed-in view of the 'drawing tip' of the smaller line. It shows the current wind movements. In addition, the line moves faster and grows larger as the wind blows faster. The colour also indicates the wind temperature.
A purple "cross-line" appears at every midnight, to show the length of the different days wind movement.
Eventually this visualisation became a 3d visualisation:

Hmm…it looks like things are taking a while to load. Try again?
