A month and a half between posts might seem excessive but hear me out! I could’ve just posted another static map image but I’m trying to push the envelope a little bit so I thought, “Why not a video?”

Unfortunately, adding a time component introduces a whole bunch of new complications. First I had to alter my code to Produce output based on a temporal sequence rather than a single point in time. After that I had to Figure out how to produce composite images so that I could add things like the time/date stamp. Then I had to figure out how to actually encode the video. Following that, the clunky user interface needed to be updated in order to accommodate the new features. Then I realized that the data didn’t include any duration information so I had to figure out how to extrapolate it. And then I had to run the extrapolation routine over the whole database which took weeks, no doubt owing to my weak SQL.

Anyways, I find the first product to be kinda soothing and hypnotic and leaves me thinking about what else I could do with it. So without further adieu here’s 24 hours of all C4S calls over Halloween, each call (red dot) growing larger in diameter the longer it remains active:
