So are you sitting there with your finger on the shutter release waiting for patterns or what? Frame grab from video? Webcam taking a picture every second? How'd you do it?

Actually, when I first started noticing patterns and got the idea to post an entry about them, I made up a quick little "spreadsheet" type diagram, and for about a week I would observe different patterns, and when one would come up, I noted the time, and filled in the circles to re-create the pattern. Then yesterday, I selected a few patterns to take pictures of, and I propped my camera in a set position, and had a notepad saying when to take each photo.
I have to admit, I had put the wrong time in my notepad on one of them, and when I took the photo, I was like "um, that wasn't anything cool"... then I realized my error, and rather then waiting for the time to come again I just adjusted the clock. Then since I had lowered my standards to get one photo, I did it again for 2 or 3 more as well. But most of the photos were taken at the correct time, single shot, no fancy setup.

Those are really cool patterns, a lot of free time albeit, but really cool. Not too many people have documented pattersn ike that in an LED display. I like to watch my digital clock in my bedroom, or on the microwave, for specific times I find interesting, such as 12:34:56 and 1:11:11 on 1/11 or the best I remember was 10:20:01 on 10/2001. That was a bit trippy. Won't ever happen again, you gotta capture and enjoy the little things in life or else go insane!
