Notes (Roving Rube): Sometimes the sky gods will step in and project some drama onto an otherwise placid exterior, as seen here on the W.R. Grace building.

In Detail, Olympic Tower, which most often appears as a sheer black monolith, gets some dynamic range courtesy of the sun and a pair of cottonball clouds.

Alternate View shows the Trump World Tower with a temporarily Michelangelo-like exterior.

One wonders if one day developers will be able to amplify the effects of sunlight with glass panels that could react with variable patterns, instead of counting on cloudy days. Or maybe respond more to variations in temperature, like a mood ring.
