Should still be there
Articles still have a Facebook Like button, comments still have the jaunty thumb. Sometimes takes a bit for them to show up, though. But if you're not seeing them, let me know.
Fascinating
The panels (well, some of them, at least) appear to cast shadows of a different hue than one might expect.

One possibility - the
One possibility - the coatings on some of those panels may be strongly refractive. Passing through, the light would be spread out according to its wavelength/color - like a prism. The camera/your eye would see only a narrow slice of the refracted light (especially from a distance, as in those pictures).
If you moved the camera's viewpoint, you might see those panels seem to shift in color - or different panels might appear mis-matched to their 'shadows'. It all depends on the angle - eg check out the difference in color between the top and bottom of the red/orange panels.
The concrete surface is so irregular that it mixes all those wavelengths back up, so the reflection off of it is nearly the full combination of all the wavelengths transmitted through the panel (that's also partly why the 'shadows' appear so much brighter in several cases than the apparent color of the panels themselves).
Hmmmmm.....
This looks interesting. Let's see what it looks like when it's all finished!
