Made a little program because I got bored. It induces the McCollough Effect.
While the wiki says you should look at each image several seconds at a time it didn't specify so I just used 5 seconds intervals.
You will first be shown a black and white image with horizontal and vertical grating for 10 seconds. You will then be shown a red with horizontal grating, then a green one with vertical grating each being shown for 5 seconds for a total of 3 minutes. The same black and white image from the beginning will be shown again at the end. If the Effect was successful the image should look slightly different now.
To exit the application at any time press escape.
PS: The application runs in full screen.
