Star pulse #sphere

u/deobfuscate

I cannot explain with words how cool this is.
u/donbright

if i undersand it, the "twinkling" really adds alot. they aren't all the same size of white particle?
u/rodrigo.siqueira

The "twinkling" is given by the particle size (2 last parameters of x.clearRect). Pixel size is defined by 3*S(i)+1, so it's between "3+1" and "-3+1" and the "i" makes it almost random for each pixel. An extra twinkling effect could be made by adding "t", but I thought it would be too exaggerated. You can try by changing to: K=5*S(i+t*4)
