From the Last Hour...
This page is like a clock that shows only half minutes. Each picture is a half-minute tick. The number at the start of each row is the minute of the first picture in the row. Each picture to the right is 30 seconds later. Each row down is 3 minutes later. Pictures after the minute of time that the page was loaded are from the previous hour.
This page is no longer updated! Think of it as a time
Technical Weirdness: The thumbnail pictures shown here were on the server when the page was loaded. Every 30 seconds, the picture for the current real-time minute (or half-minute) is replaced on the server with a new one. When you click a picture to view it full-size, you will get what was on the server when you clicked. If the picture on the server has been replaced, what you see won't match the thumbnail that you clicked.
