I wonder if there would be an easy way to make this? I thought I'd find something on Instructables but no such luck. You can buy one but they're really expensive $179 at Yanko Design.
Would be a great gift for that child in your life who is afraid of the dark. Also makes neat ambient light in a room.
If anyone knows of a way to make one of these I'd love to hear it!
Apparently, it's battery operated and lasts for about 4 hours until it then dims down and turns off.
