Many of the Anfy applets are intended as functional additions to your site. There's also a set of navigation menus that are unusual but useful. The Wheel Menu gives you a game-type interface that could be great for a casual or game site, but would likely be too distracting for business use.
Likewise, there's a variety of banner display applets that can be modified to match your site and that, when done right, may be useful for commercial use.
Two applets are particularly interesting because they can differentiate a site. One I particularly like is Anfy Paint. While it isn't Photoshop, it is fun to use. You might put it on a site to let your visitors create their own drawings.
The other interesting applet is Anfy Puzzle. You can load an image of your choice into the program. When the user runs the applet, your image is displayed and then scrambled like a two-dimensional Rubik's Cube. The user then slides the blocks back in place to make sense of the image again. It's fun and can be addictive for your users.
Useful Applets
You can also establish your own chat group using Anfy's full-featured chat applet. It functions much like Yahoo! or any other chat system and allows user profiles, private conversations, and chat rooms. It's also possible to change its look by modifying the setup parameters.
The Web Cam applet is great for putting up either sequential stills or streaming video on your site. The applet only addresses the client side, though, so you'll need to use other software to capture images from your Web cam and upload them to a location on your server where Anfy Cam will be able to find them.
