I had some colour changing LEDs lying around and I wanted to incorporate them into papercraft. I was trying to think of a scene I could make and my mind just kept coming back to this idea. Sure the Northern Lights may be an odd choice for papercraft, as it is not easily rendered onto paper, but I thought I would give it a try.
The colour changing LED projects against a white cut out of the Aurora against a black background. There are small holes in the background with a white LED in behind to give the appearance of stars. When I was looking at images of the Aurora Borealis on Google a lot of them had trees in the foreground so I added some silhouettes of trees to make it look more authentic.
