This comes out when combining particles, a forcefield, SoundMixer.computeSpectrum and some eye-candy. The forcefield is generated by perlinNoise so the particles refer to Andres sweet lightning particles. The idea of using a forcefield is still the same.
There is a fixed amount of 5000 particles in this scene. I want to add here that even 10.000 particles are possible but the creation of the stripes you see is interrupted by the number of particles that are used for the spectrum. The stripes are also built using the perlinNoise with a simple trick. If you build a perlin noise on a 200*200px image and scale it back to 400*400px you have nice rasters. I use a transformation from 100*100px to 400*400px in this case.
The color-change is done using a simple ColorTransform and also changing the additive color behaviour of new particles. Another thing is the blendmode of colors. I really like to add colors together. If you combine this with a BlurFilter you have a really nice glow effect.
In the background you can hear a very nice deep house track from MC Carlos.
Hmmm I´m getting an error saying the ByteArray class is not found :(
