I first thought of making a triangle and doing a rip off of the famous Pink Floyd cover. But I didn’t want that. So my mind went from light deflecting off prisms to light hitting elements in the sky. The natural show is called an aurora and there is one in both the Southern and Northern hemispheres, australis and borealis. The impressive lighting appears due to solarwind hitting which excite the atoms in the air causing the release of light as their excitation state is normalized. The different colors are produced by specific elements or mixture of elements. The main atoms are nitrogen, which releases green, and oxygen, which releases red. The color combinations are more or less likely depending on altitude of the action. Usually red is more common up high and green is more common lower down. I added in this fact into the elements of my sketch.
By dragging in across the night sky you can produce your own aurora in the air.
You can hit the enter key to clear the sky if you want to clear the night again.
This piece is great. The way the lines draw in random lengths to create an effect of them fading out is incredible.
Very good job with this program. It really does closely resemble the lights of an aurora. I would recommend though that you add more color options though. Blue and purple auroras are very common, but there do not appear to be any available to make in this program. Well done though!
