Loving this from the ever excellent BBH Labs blog.
Not only a great-looking game and a smart response to what would have traditionally been an advertising brief, but a sweet example of taking something effortlessly between physical and digital worlds.
(Side note: I am currently pondering the idea of "seamfulness" that I found in Oli Shaw's presentation on magic. Are products/services/platforms like this, or like Nike+ for that matter, seamless…or is it really that they have beautiful seams?)
