Many of you know by now that I love coming across optical Illusions used in real life encounters. Below are two pictures, just study the top one before looking at the bottom one.
These photos were taken in Toronto, opening day of the New Sheppard Subway Line, November, 2002. They were photographed by Andrew Gurudata at the Bayview station.
Ponder the top picture. How did they get this effect with just paint? I sort of understood what must have been done to get this effect but it wasn't until I saw the bottom photo that I fully appreciated just how well this optical illusion was done.
Below we have the same illusion but from a slightly different angle. This is really quite good. I don't know who the artist was, but since it was there on opening day I have to assume this was paid art and not graffiti.
If anyone knows the name of the artist or if any of you have other examples of optical illusion art on display in a public venue please let me know (and include images if possible).
