Hokusai's Thirty-Six Views of Mount Fuji are his most well-known collection, and the first print in the series is The Great Wave Off Kanagawa. I had been contemplating this 36 Views of South Waterfront thing for a while (as evidenced by this post), but in light of recent events in Japan, it seems all the more apropos.
These two below (#6 and #9) were taken from nearly the same spot in traffic, just a few days apart, but the difference in color is apparent. One of the things I love about this collection of buildings is that they appear to be a different color every time I pass them. The weather and the time of day do so much to change their reflective facades.
