I have observed a strange infinitely repeating pattern that seems to be created whenever a line (constantly changing colors) is rotated about it's center by various decimals of degrees. I believe it happens because of how pixels on a screen work. when a line is angled it is not still perfectly straight. It has various cracks to say which when observed from a distance make it appear slanted but up close are revealed to be small split up sections. I think it is created because when a line is rotated and it changes colors it will imprint different colors in different areas more than once and in some areas only for a split second. when they overlap they create the peculiar and quite beautiful if I might add illusion.
I would recommend turbo mode once you've gone through 1 and .1
