Hello.

I found a cool fisheye effect using Javascript at the Dojo Toolkit website. Check it out, it's neat, but I'm not sure how practical it is.

I've previously mentioned the .NET Image Filter Library, and I highly recommend it to anyone interested in learning about programmatic image manipulation. The library is well-documented in an easy-to-follow CodeProject article by Andrew Krillov. You can find it here: Image Processing Lab and Motion Detection. I even created a fisheye filter for this API, which you can find here: Fisheye Example
