Creating a screen-saver looking like animation

I was wondering if anyone ever came across to this and might be able to redirect me to a useful link about making a screen-saver-looking-like animation to use as the background of an arcade game i’m making. This video https://www.youtube.com/watch?v=EQd33xmC_Ic describes exactly what i am looking for. A loop with random colors and particles in a space-looking-like environment. Anyone came across with this before ? Hopefully i can get some help because this has most definitely been implemented before.

Edit: I found https://stilghar.wordpress.com/2013/03/03/particle-systems-part-3-unitys-shuriken/ this link but it is unfortunately done in unity, but i added this here just to show you what i am trying to find in more detail
