On another forum I frequent, someone posted a link to a fake tilt-shift video and asked how it was done.
Previously I had seen still tilt-shift images and googled around to figure out how to create them using Gimp. Lots of references like this one at Gimparoo, or variousblogs. One thing in common these had was using a gradient mask to blend a blurred copy with a non-blurred copy, or in the case of fancier efforts that use the focal blur plugin, a gradient to drive that plugin.
To me, these efforts left a bit to be desired, as the gradient would leave odd artifacts of focused bits of objects crossing in front of the focal plane gradient point. I figured a good way to get around this would be to construct a complete mock depth map based on the image. Here is an example of a before image, and the fake tilt shift.
Stumbling through the quagmire of the internet I came across a little project by Lukas Vojir to collect a series of user contributed "monsters" made using Processing.
It has been a while since I played with Processing, so dusting it off, and grabbing a few of the examples (most notably Blink Eye Monster) I created Ouroboros - the processing monster that eats its own tail.
While surfing about the net I ran across a nifty tag cloud implemented as a flash movie, WP-Cumulus. Unfortunately, it was a wordpress plugin[?]. Fortunately the creator, Roy Tanck, was kind enough to not only open source WP-Cumulus, but to provide tips on how to incorporate it into other web sites!
So I hacked it into my local blog (sorry for the down time ) and got it working with hard-coded parameters, then migrated it into the freetag plugin that Serendipity has. Garvin (the creator of S9Y) made a few improvements, and it is now bundled into the application, and available via Sparticus, the S9Y online plugin manager!)
