Above is a video generated by a couple of programs I wrote a few years ago. One is a physics simulation of fireworks and the other is a simulation of accelerating raindrops. The colors represent nothing, they are purely for entertainment. However the firework program generates new neon colors for each firework. They are not preset colors in any way. The rain program oscillates through all of the colors in the RGB-256 color pallet. Unfortunately I had to reduce the image quality to make it load quickly (1024x547). If you would like to see the source code for these programs or my multiplayer online snake game you can visit my github account.
