Speed of light on Arthur's Seat #blipthefestivals

Part of the Edinburgh International Festival, the NVA Speed of Light was one of the more unusual events. Groups of us tramped up Arthur's Seat in the dark (rather scary) equipped with poles that doubled as torches. Across the hills, runners in costumes studded with lights ran across creating patterns.

At one point, runners streamed past us. You can see a walker on the left, but just the streams of light left by the runner.
