If your room is in need of a make-over and you would fancy saving some time on repainting, try constructing a rainbow machine like Dutch artist Edwin Deen did. All you need is a garden sprinkler, a few meters of hose and color pigment of your choice.

Operating like any ordinary garden sprinkler, this rainbow machine sprays the selected bouquet of colors to cover all the walls around it.

This simple yet dazzling idea was even on display at Barry at the W in Amsterdam only a few days ago.
