I saw this and felt it is a significant work for discussion and thought. The piece is called Grey Keys.
Firstly, how very clean it is. It starts simple and ends simple.
Secondly, choice of music. The designer has really analyzed this piece, felt the space between notes and given them shape.
Thirdly, the palette. Did you notice the specs of black playing against the background? The tonal range is simply between black and white, I would guess there is no absolute Black or white in there, if so it's used judiciously.
What is so pure about this work is that it is using basic elements, circles and lines, to constantly grow while never repeating itself.
