SparkleTrail1
This was a little hack that left a trail of glowing sparkles behind any motion on the video feed. There are probably much better ways of doing this in 10.5.

HighlightColor
This compositions filters any colors that aren't close to the target color out (replacing them with black and white), and replaces any color that is close with the target color. This makes things that are close to the target color appear to stand out.
Psychadelic Edges

MoneyForNothing3
One of the reasons I like the sobel filter for edge detection is that it makes it really easy to find the gradient of the edge-- that is, which direction the edge is pointing. This composition was originally just a debugging tool to make sure the sobel was accurately differentiating the edges. But it looked kind of neat on its own-- kind of like the glowing lines in the old "Money For Nothing" video by Dire Straits, so I put it up on the site.

AdaptiveThreshold2
The "adaptive threshold" technique finds a local value on which to threshold the image. While it's usually used to pull text off a book scanned on a flatbed scanner (where the brightness can vary across the image), when used on video it produced a kind of woodblock-print look that I thought was fun. It's also not very sensitive to lighting conditions so doesn't have to be tweaked as much.

Threshold2
This composition simply thresholds the input video at a certain level, and assigns one color to brightnesses below the threshold and another to ones above. But it can give a pretty funky look if you pick the right colors in the right lighting.
Take On Me Video Effect

TakeOnMeVideo5
This one is purely about the edges... but with the right lighting and with some tweaks it kind of looked like the stylized drawing in the video for "Take On Me" by Ah-Ha. So I added the spinning thing.
