Senseless beautiful and beautifully pointless

A swarm of thousands of colorful particles buzzing uncoordinated across the screen. The changes, moving one finger on the screen. A finger follow the particles like a sore thumb Starenschwarm in geometric patterns. With two fingers to dynamic rotation patterns form depending on the location and spacing of the fingers, in three there are colorful maelstroms and four fingers you get back down stable, moving patterns. What is or is the whole? I do not know, but it looks just beautiful, alive and mysterious how to conduct the pattern. Just for looking at what!
