Optical illusions in art.

Some really cool pictures in this 3rd part of the series on DarkRoastedBlend

This is pretty interesting from part two in the series. I have seen these before on another website.

Have a look at this photograph of Neuchatel, Switzerland. How long would it have taken Felice Varini to put the red lines there ? Five minutes, with a pencil and a ruler ? I don't know exactly but it would have been much, much longer. You see, the red lines are actually painted on the buildings. He just took buckets of red paint and got into town, as you will see below. This illusion only works from one exact point of view.

I love this one! (From part two)

Stare at the black cross in the center. Within seconds, a green ball will appear. And a few seconds after that, the green ball starts eating the purple balls, until there's nothing left !
