iDisco is available for iPhone and iTouch, and flashes 7 different colours at varyingly intense speeds to try and confuse you eyes!
Choose slow, fast or extreme to see how your eyes react, or choose your very own custom speed.
Feel free to post your comments, and if you like it then rate 5 star!
As a precaution this app should not be shown to any person with epilepsy or another similar condition, as it contains flashing images.
