This is seriously good design. I’m impressed.

Very nice. I’m assuming it’s outdoor?

Von K… not sure actually… it would work well in subways as well.

great concept! simple and effective.
on the flip side – if this is for outdoors who’d have time to lean over and read anything vertical? and even if its a 2 page magazine ad, the text is too small…. maybe in print it would be clearer than on screen
my 2c

me likey :]

Great, just great. Now I have to take another ad out of my book….I think I’m being watched

excellent concept, as long as people know that audio-books exist in the first place. And what soundwaves look like. Otherwise….

soo cool.
