The facade of Rådhuset...

...has been decorated via the light installation Resonance - exciting things are happening with lights and sounds when you step or jump on the plates - a popular place! This artwork is made by SMASH Studio in Stockholm for the light festival Allt ljus på Uppsala.

The snow we have got has not been good for all light installations, for example this one which has now been totally covered by snow. 
However, thanks to a heating system at the square with Rådhuset there has not been any big problems.
