My Current Favorite

In terms of meeting "really new media," few I've seen recently can top Nokia's effort it titles the "World's Biggest Signpost."

The installation is strategically very sharp, with the user involvement not simply a standard contest or game, but rather is directly contributing to delivering/enacting the key message. What's more, the monumental scale  underscores the power of a user's finger digitally enabled, while the sheer fun you can see on people's faces (rather than stress, as in many competitive games) sets this one quite a ways apart.

Finally, this project also demonstrates what to me is the next frontier in digital thinking: Namely, that digital isn't simply what happens virtually as opposed to in the "real world," but it's how the virtual becomes mapped onto the real.
