Designer Tim Holley’s ‘Tio‘ ghost is a wall-mounted light switch system which enables children to demonstrate their knowledge of energy conservation to their families, while encouraging their role as ‘energy champions’ of the home.

‘Tio’ shows he is happy and green when household lights have only been on for a short period of time — but the longer the lights are left on, the angrier and redder he becomes — showing he is truly lighthearted and all business at the same time!
