3D-Art at Shibuya Hikarie

A couple of pieces of 3D floor-/street-art are on display in a highrise near the train station I use for work.  Stopped by to get a couple of pictures today.

I was surprised by how many people didn't even notice that it was there. The guy in the yellow jacket who looks like he's walking across the stone steps?  He didn't even realize he was doing that.

I wish I could tell you why they went with the sweets theme.  Reminded me a little bit of playing a game of Candy Land.  Also, a giant diamond ring, a bear with wings, and an upside-down wine glass?  Beats me...

You'd actually have to be a bit taller than I am to have the right viewing angle, but it's still a pretty good optical illusion.

And here's another detail of what the image looks like from a different direction.  You can see the "stand here" spot near the blue cone at the top left.  I feel like it must have taken equal parts creativity and technical skill to put this together...
