Will and Guy love 'playing' mind games with these circles. Take the time to sit back and let the primeval parts of your brain take over.
I find it difficult to get my head around these 4 perfectly round circles.
Ferris Wheel - Another Circle Optical Illusion
This reminds Will and Guy of the London Eye. It's truly mesmerising the way that the blobs or pin-heads seem to rotate clockwise. While
our brain tells us they are still, our eyes are telling us that there is a circular motion.
Neat Swirly Circles
Lego Wheel Illusion
Can you see this wheel turning? Guy cannot, but Will says it's turning clockwise.
Parallel line - Classic optical illusion
The middle, red lines are truly parallel, it's the radiating lines that cause the illusion of bending.
Do you think that the central rod really exist? This particular 3-D illusion is known as the 'Devil's Tuning Fork'.
The trick to this illusion is to take a step backwards. Guy needed to go back 15 feet before I could see Marilyn.
