I made this cloud lamp for my daughter her bedroom.

It is made from some plywood and a LED strip.

Using a jigsaw, I cut out the cloud shape and refined it with a router. Then I sanded the front and made sure there where no sharp edges.
On the back, I affixed a similar shape with a smaller offset. Then, I attached an LED strip to the side of that shape.

The LED strip is adjustable in brightness, making it ideal as both a reading lamp and a gentle sleep light.
