Viral Marketing to Creatives?

I’ve recently been coming across more and more viral videos and don’t see many that are aimed towards “creatives”. I did stumble onto this pretty promo video, PunchPunks (http://www.punchpunks.com), for PunchStock’s new rights managed collection that is pretty cool. Free magnets even…whoo hoo!

Anyway, anyone come across any other promo videos like this for ad agencies or design shops? Thinking about maybe experimenting with something along those lines with my own studio.
Thanks :slight_smile:
