So here's how it works:
> Turning the aperture ring raises the "Diaphragm Bar" behind the lens. At f/2.8 it's completely below the lens opening, and at f/22 it's just below the lens centerline.
> When the mirror rises, it drags this panel up with it; the odd shaped hole in the middle is the shutter opening. The mirror/shutter rises just as fast as its spring can whack it, and returns at the same speed as soon as it reaches the top.
> At f/2.8, the shutter is open for the entire distance of travel shown in green above - it takes about 1/60 second to cover this distance. But at f/22, with the DIaphragm Bar up where the purple line indicates, the shutter doesn't open until it reaches that line, and it closes as soon as it passes that line on the way down. The entire movement takes the same time as before, but the open time is only the time that it takes to travel the distance shown by the purple arrows. Assuming that the speed at f/2.8 was 1/60, this works out to about 1/500 second.
> The aperture at f/22 (and at all other settings except for f/2.8) is in the shape of a triangle with its point at the top - the top 2 sides are the edges of the "roof" part of the shutter opening, and the bottom side is provided by the Diaphragm bar.
It's actually just a little more complicated than this. In the above description, the f/22 opening is not centered on the same axis as the f/2.8 opening, and in fact if the Diaphragm Bar actually went as high as the purple line it would block off the center of the lens. So, in addition to all of the above, at the smaller apertures, the mirror/shutter is actually stopping its upward travel earlier than it does at full aperture. How does it do this? In the view of the Diaphragm Bar at www.flickr.com/photos/rick_oleson/53225547915/in/dateposted/, there is a second, gold colored bar that's coupled to the Diaphragm Bar, with a bent-up tab at its tip. As the Diaphragm Bar rises, this gold bar comes down - the tab at the end is the stop that the mirror strikes against to stop its upward travel. The two bars are coupled together so that the mirror's stopping position produces a centered triangular aperture opening at all settings. Dang.
Whoever did this will probably never be famous - but he was good.

Times Square at Night. Signage is mandated by zoning ordinances that require building owners to display illuminated signs, the only district in New York City with this requirement. The neighborhood actually has a MINIMUM limit for lighting instead of the standard maximum limit. Officially, signs in Times Square are called "spectaculars", and the largest of them are called "jumbotrons". This signage ordinance was implemented in accordance with guidelines set in a revitalization program that New York Governor Mario Cuomo implemented in 1993.
Times Square's first environmentally friendly billboard powered by wind and solar energy was first lit on December 4, 2008. On completion, the 20 Times Square development will host the largest LED signage in Times Square at 18,000 square feet. The display will be 1,000 square feet larger than the Times Square Walgreens display and one of the largest video-capable screens in the world.

(I asked, and the "World Famous" designation was given many years ago and few others have the title. Pretty cool.)
