At 3meverywhere.com 3m is boasting about the 50.000+ innovations. In a nice way, however, because the site is actually a lot of fun.

You enter an interactive movie telling a story, in which you have to find and pinpoint certain hotspots with your mouse – these hotspots obviously indicating 3m innovations. You’ll also get a short explanation every time you find one.
And if you don’t find all 15 you’re supposed to, you get a second try – while the game remembers the one’s you found so you only have to hunt down the spots you’re missing.
