<seadog007>: @pcchou Make a scene of simple room/wall having a light bulb and a switch. Make the switch control the light bulb. On one click it switches it on and on the other switches it off. Brownie points for multiple switches and lights. For instance: http://bit.ly/1NQj27P . It has a simple toggle switch that makes the bulb turn on and off. HINT: Make use of JavaScript.
