Surprisingly, this effect is not common although it was described in Graphics Gems. I have enhanced it somewhat, so you can choose its frequency and offset.

This filter produces a very wild effect. Even slight changes in frequency and offset can produce drastic changes to the effect. It is cyclical, that is, the frequency of 1 and 256 produce the same result. Similarly, offsets of 0% and 100% are identical. The frequency of 1 and offset of 0% produce no change in the image. As you increase either slider, the image changes considerably. As you go above the frequency of 10, or so, the image turns into complete noise.

But, do not stop there! Around the middle (frequency 127, offset 50%), the image, while still noisy, becomes visible again. Increasing the frequency even further produces more noise. But as you come close to the other extreme (toward the frequency around 250-256), new wild effects take place.

You may want to play with this one a bit. You may also write down slider combinations that you find the most intriguing!

Just to give you the feel of Pixie Dust Pro, here's a screen shot of this filter with all channels set to random options:

Here's another one produced with the Saw Tooth filter of Pixie Dust Pro, this time with these slider settings: Frequency - red = 251, green = 254, blue = 127. Offset - red = 34%, green = 0%, blue = 50%. Effect Opacity - red = 137%, green = -32%, blue = 11%.

I discovered it quite accidentally, by simply clicking on the Random button. As I said earlier, these filters go beyond what similar filters by other authors do. The Random button is a nice way of discovering interesting new effects.
