   'Olo' is discussed specifically in the video. Olo was generated by   
   using microlasers to stimulate one particular set of cones in the   
   retina.   
      
   This video attempts to do something  similar by having you stare   
   at a (more or less) red screen for a minute to bleach out the   
   other two cone types, then switching to teal. This means that   
   the M-cones (the ones the laser stimulated) are way more active   
   then the other exhausted ones, and for a second or two you see   
   an approximation of olo.   
      
   Its pretty neat.
