I was walking through DuPont Circle in Washinton DC last week. I stumbled upon Axis Salon. I was so intrigued by the glass storefront that I had to hang up the phone and stare. The salon front was COVERED in QR codes!!!

Instructions to download: (they recommend 3GVision's i-nigma)
They should be telling consumers more about what phones are compatible, probably. There should probably be more instructions, but at least they OFFER instructions.
Scan the code ... link to a Web site with a coupon.
It's pretty basic, but very effective. They must have a lot of people asking. It's certainly driving buzz - I mentioned it to a couple of people I met in DC, and they knew about it. Partial instructions available. Lack of compatibility with most phones ... maybe an issue, but those who don't know about 2D codes are probably also less likely to ask. Fun.
