I've always been fascinated by kaleidoscopes. I found a site here
to make one using one of your own photos. Here's a screenshot of one I made. If you want to use the same photo, here is the url you will need http://static.flickr.com/43/150168601_d8e26e6382.jpg
I only wish the site would allow for a flash download so I could post the actual working kaleidoscope on my blog.
