Image Reflector
If you're like me, you've done a lot of image manipulation. In Photoshop, Paint Shop Pro, Illustrator, Freehand, I've never found a tool that reflects well. So I made one.
You can load an image and reflect either horizontally (left to right or vice versa) or vertically (top to bottom or vice versa). You can do it any number of times, creating immense and intricate tiled patterns (or small cute ones). Best of all, each time you reflect, the image is resized to fit your action and preserve symmetry, making it perfect for tiling. No other tool I've found does this. Please don't redistribute, and if you could credit me for public use of your results that'd be great.

You need Java -- the JRE or SDK. If you don't know what I'm talking about, then you don't have or need the SDK.
