Perfect for a 13 year-old's bedroom! I asked my son if he would recommend this light and he said everyone should have one - and suggests you paint the walls white for the best effects. I assume the novelty will wear off but right now he says it is super-awesome and is fascinated by the way changing the light in the room changes the colour of other objects. Frankly the flashing effects are a bit much (although they are probably entertaining the neighbourhood), but I can't fault the value for money. It does do normal white light too!
