this is just 3 shapes changing colour fading in and out and then the same 3 shapes fading in and out but backwards while there is a constantly changing background. that triangle that you may see at times at the bottom doesn't exist. its an illusion from two shapes overlapping. and depending on when you stop the project, the thumbnail will look like one of two results every time. and also, the further in you play the project, it looks like all the shapes are staying there and only changing colour. in reality, they are still all fading in and out.
