There is an annual exhibition in Linköping named "Winterlights". These are some of the light art installations that caught my fancy.
Many of them are moving, some are including music, or shifting and changing over time, meaning they don't really lend themselves well to picturing. It's hard to say "oh, purdy" of a picture that reflects the way light shifts and slithers as it 'walks" across a building, leaving an interference pattern behind it.
It just didn't lend itself to pictures. Which I liked.
