There is a major national campaign taking place in France right now against Aids (or AIDES/SIDA en Francaise). This campaign came to my attention thanks to the great work of X-Prime, a French interactive marketing agency. X-Prime produced a flash sitelet entitled Tous Les Rencontres Sont Possibles as a supplement to the public awareness campaign.
The flash animation itself is a bit pornographic (I wouldn't recommend watching this at work!) but it is just emphasizing the importance of using protection during sex. The website itself is www.touteslesrencontressontpossibles.com which translates into "All Encounters are Possible" as in you should always be careful. The site's mission is primarily informative, seeking to educate people on how they can/cannot contract aids.
One sweet feature about the website is that you can see all of the other people that are on the site with you. The other users appear as floating symbols located above their name. You can't interact with the other users that are on with you, but I like that. I can think of about a million other places I'd rather meet someone than a site explaining how you can and can not contract aids. So good call on leaving that feature out X-Prime!
All in all, the site is really well done.
