Special Go board
Keywords: Humour
A special Go board. Can you see the white and the black stones? But wait - what is white, what is black here? :)
That hurts! :) LoP
This may happen to you if you play too much GO...(I've found the above picture on a website about visual illusions.) MarkD
[edit]
Technical details:
This is called a Scintillating grid illusion
and interesting if the lines would not be straight but wobbely the illussion would not
occur
