Thanks to Jonny Baker for this shot from the Dan Flavin exhibition at the Hayward Gallery in London.
Love Flavin's work - really like the way he uses light. Inspirational.
What's even cooler is that there is a soundscape that goes with the exhibition by Greyworld. You can download it as files or as a podcast...or if you are lucky you could borrow one of the Apple-donated iPod Nanos for the experience.
