This site from Stimorol Chewing Gum allows you to challenge others to a virtual kiss off. Choose your character and then use a series of sliders to select your style of attack. Friends are invited to the challenge VIA email and the resulting battle is played back as a video.
I took this video screen capture to show how the process works. Of interest is the video service I used for the upload, Vimeo. They now support HD and 16:9 size format.

Props to my boy Detroit Dave for turning me on to this.
