Two examples of the Peripheral Overflow illusion with shades of blue as an example.
- Open the video fullscreen.
- Keep your eyes fixated on the centre of the screen for a good amount of time (tens of seconds to minutes).
- The first example contain no fixation spot, the second is identical to the first, but it does contain a fixation spot. Some people find that the illusion works better without a fixation spot, but you can try out which works best for yourself.
