From my parents - I thought that this was quite clever.

Take a look at HEMA's product page. You can't order anything, and it's in Dutch, but just wait a couple of seconds and watch what happens. Don't click on any of the products, just wait and see what happens. And be sure you have your sound turned up. [Edit: Apparently things that are soft to me are very loud to other people. Whoops. Make sure you have your sound turned on, but to a more moderate volume than originally stated.]

From Tim Smith (I agree, and think groups that want to make things that will quickly be internationally understood should take note):

350.org, a climate change activist group, put together a totally sweet and basically wordless animation to describe their mission and its urgency. I think it’s really well-done.

(Marketing. I'm interested by marketing. I think I'm turning into my father in some ways - ways that are very much not such a bad thing.)
