Thus far I have seen every gif blink except, for someone hits a hole-in-one, earthquake 4 and old faithful erupts. I'm tempted to open the gifs and check the frequency. EDIT: I have looked at GIF format: http://www.onicos.com/staff/iz/formats/gif.html http://www.onicos.com/staff/iz/formats/gif.html Then I opened the image with fhread and found the offset for the delay time. Look for: Delay Time (1/100ths of a second). ( Since the delay time has only 2 bytes reserved that means the max delay would be 65535. That is why some gifs have more frames than the other, when by logic all would need to have the same count ) Then I opened the image with photoshop which shows every frame on a separate layer. Then you just multiply the delay with the number of frames. I got the ratio of 3786.72 to 1 for earthquake-1 to earthquake-4. e1 is about ~3s so that would make e4 occur every ~3 hours. The ratio should be correct. But my seconds calculation was off by a factor of 4 for some reason. Maybe I missed some format specific stuff. You can try it for the rest of the GIFs if you want. EDIT2: A very quick estimate, looking in the other files: hole-in-one: ~50 minutes old faithful erupts: ~4 hours Wiki says 45 to 125 minutes. http://en.wikipedia.org/wiki/Old_Faithful http://en.wikipedia.org/wiki/Old_Faithful

Yeah, how do you do that? I saved the gif and opened it in apple preview which show the frames but not the frame rate. Photoshop perhaps?

  On the Mac, GraphicConverter[0] has been my go-to app for this kind of random graphic stuff since the mid-90's (wow, it's a 22 year old app now!). "Movie Information" in the windows menu says there's a 300 second period on the Old Faithful GIF. [0] http://www.lemkesoft.de/en/products/ http://www.lemkesoft.de/en/products/

    That would be far too high a rate. Old Faithful erupts approximately every 90 minutes, or 5400 seconds (though it can vary quite a bit -- 45 - 125 minutes): http://en.wikipedia.org/wiki/Old_Faithful http://en.wikipedia.org/wiki/Old_Faithful

oldfaithful.gif has a 93.9 minute delay (8 655 second frames, plus a 392 second one). Which is about right. (ImageMagick's identify program outputs the frame delays when you give it -verbose. Units are hundreths of seconds.)

  You can take any tool that can process .gif. The fun part is doing it yourself and learning something in the progress. I downloaded a .gif editor, but decided to not use it.

The GIMP (http://gimp.org http://gimp.org) is very handy for editing animated GIFs. Each frame is loaded as a layer, with the frame's duration appended to the layer name.
