that is awesome the purple balls totally disappear to me and there is only a single green ball. thats one of the coolest optical illusions i have seen in a long time. the last one i see was a bunch of spinning rings that if you stared at for a while and looking and anything like your hand or something it would grow bigger and smaller right before you eyes. really a trip for sure.
