Did you know if you draw on a lightbulb, that the design will cast on your wall at night. How adorable for a child's room -- Even let child design their own lightbulb and watch their art project on the wall!
Penny Floor - don't know if I would have the patience for a whole floor. but a coffee or patio table would be nice! Also an easier way to do it is to put out the pennies then flatten then by, I don't know, maybe a broom or some thing.
