Rendering Realtime Movies of your stuff...

So if you're doing some huge graphically intense thing that renders out one frame a minute or something insane like that, then the extra marginal time to save a jpg for that frame isn't a big deal at all.
But if you are running something in realtime (say in sync with a live video feed) then the time it takes to save a jpg for every frame is unacceptable. There is, of course, a better way.
HyperCam http://www.hyperionics.com/ allows you to record in realtime a portion of your desktop. However the free version sticks a watermark in the top left corner, so be sure to select an area an extra 20px high or so  Saving it as uncompressed video takes less processor time (as im sure your sketch is going to want the CPU time)
Once you have your uncompressed video use VirtualDub http://www.virtualdub.org/ to cut off your top margin and any extranious goo on the edges, and then compress.
You're left with a good quality realtime video of your sketch in progress!
Here's my own example:

This is very cool! These are some really handy resources. Your sketch is great too.

You could also save an image of your sketch after each iteration (which would take a lot of disk space!) and then convert it to a movie such as with QuickTime. This would ensure that no frames are skipped due to computer lag.
Perhaps that should be a feature request - the ability to export a sketch as a movie.

Correct, I refered to that in my first post. The problem arises when you are writing a image to the HDD every 1/30th of a second. When you are using a live source you can't just slow things down to catch every frame. In realtime framedrops happen, but this was pretty effective if you ask me.
