Just for fun: color illusion

Post by angros47 »

Run this program, and when it displays a circle, stare at the cross in the middle. Don't move your eyes away from it. When the screen will become white, for a moment you will see a yellow circle

Code: Select all

screenres 800,600,32


line (0,0)-(800,600),rgb(255,255,0),bf
circle (400,300),150,rgb(0,0,255),,,,f

color rgb(0,0,0)
line (400,280)-(400,320)
line (380,300)-(420,300)

sleep 20000
line (0,0)-(800,600),rgb(255,255,255),bf

inkey
var x=input(1)
