High School Yard Steps

After 12 years of closure, the steps from the Cowgate to the High School have reopened. They have been refurbished and an art installation by Callum Innes. When no one is on the steps there is a loop of pre-recorded movements on a background of red, orange, green or blue. If someone goes up the stairs their movement appears on the screen. I only saw people walking by and don't know what that is like.
