There is something magical and other worldly about a light instillation. I saw a couple of really great ones this year at David Zwirner gallery. I took my 6 year old son, Luca, to see LC 71 NY DZ 13 DW by Doug Wheeler and he loved it. We felt like we were walking on the moon. Unfortunately I missed the Madison Square public art project Scattered Light by Jim Campbell. What an awesome gift to the public.
