I've created a show-off app for my recent implementation of face detection in flash. If you've got a webcam, you can play with it now. It's also got "Load from URL" functionality, but you've got to find a server that has a permissive crossdomain.xml file. Supposedly flickr and yahoo have appropriate permissions, but I've not tried them.

If you're running firefox, the "export to page" option should insert the altered image into the html so you can right-click-save it. IE doesn't seem to work. I may integrate export to ImageShack in the near future.

Anyone interested in helping with optimization of the face detection library? (I'm talking to you: rachil0, MyFriendIsATaco, 691175002, and others)

So that this thread isn't all about me, please discuss your own projects which show off cool stuff with really dumb demos.
