A simple Core Image kernel based effect, that allows for offsetting the R, G and B channels of an image on the x and y axis.
Probably quite similar to Memo’s version from way back in the day, but I can’t seem to download that one 
Detailed Info:
Controls:
Pretty self explanatory: X and Y offset for each channel.

Thanks. Have had some fun with this one. Good for ambient layers.
Yo, you can do this in one CI kernel, rather than three…
I’ve got something similar at http://kriss.cx/tom/2009/05/rgb-shift/ . Should be simple to add support for different offsets per channel.
@ AVicious: thanks for the comment! glad you’re digging the effect.
@bangnoise… heh, yeah, figured that would be possible. I gave it a try before, but my CI programming skills were not up for it yet … really like the rotating effect on your version!
