7 Computers linked seven huge swings (5m high) for adults.

Each swings are illuminated by seven different colors when their angles are all different (almost impossible though). A work made to represent " cooperation through non-cooperation". "Light / Depth" is for boys because surfboarding, the origin of skateboarding, has its rise in a ceremony for attaining manhood. "Over the Rainbow" is for girls since swings are taken as girl's playthings.
