A very hard to read website but cool way of using the error correction capabilities of QR codes.
Google Translate can help.

I created http://qrid.it, to combine the use of short url’s and qrid’s. There’s also a free module for the Joomla CMS available.

Yeah, I’m having trouble thinking of many situations where a blinking LED would be superior to a simple, static QR code. There are a vast number of use cases it simply wouldn’t cover.

Deutsche Bahn, for example, is now doing purely electronic tickets where you just get an image containing a QR code on your phone, and the conductor scans it in.

QR codes are a very cool technology. Thanks to the Android platform this technology will be more accessible to many more people in the coming months (after everyone buys a smartphone this x-mas). It’s pretty useful for a variety of applications. I posted one on my facebook account and everyone thought it was an ink blot :-). Oh well, my friends will remember my post if this becomes popular here like it has in japan. I’ve been working on some tools to make it easy for people to experiment with the technolgy for personal or business. Should be in beta soon.

I don’t think the LEDs will take the world on that soon. The good thing abot qr’s is that you can put them on paper, on web-pages, on stickers, clothes and what have you. A LED is a bit more stationary in my idea of how the world acts.
The fun thing about QR’s is that they are real teasers and some people just cannot resist the urge to check them out and see where they end up when they see a QR (kind of like me with small roads in the woods).

Firefox extension I find really useful:
https://addons.mozilla.org/en-US/firefox/addon/2780

Makes current page or links into a QR code on the spot without opening another window.

> What if you don’t want to attach a blinking light to whatever the heck you’re advertising?

CCD cameras are able to se IR LED’s pretty well. Sometime when you’re bored, point your TV remote at your phone’s camera and see what happens.

Power consumption isn’t really an issue… you could run the lights all night long on a relatively small battery charged by a solar panel. In fact, my grandfather owned several billboards in areas not served by power utilities, and they ran the billboard’s lights off solar charged batteries. Some blinking LED’s are pretty trivial at that point.
