My experience design class last semester at school built a bunch of dynamic interactions based around QR Codes for the student exhibition. It was a process that nearly drove the lot of us crazy, but the end result was pretty cool. Here are some pictures of my contribution, but to see more about the whole deal, go check out the site our Professor put together.

Long story short, the site was submitted for us to the ADAA and we've made it a fair bit of the way in, we're all fairly pumped. Who knows how it will shake out but still pretty cool.

There's three things left I'd like to add:

1. One is a silly easy one I just keep forgetting when I have Coda open, code formatting, kind of essential. I think I'm just gonna add a BB style tag for it, ie [tag]codez[/tag], though I could see if theres a browser intent like I'm using for the links and stuff.
   
2. Stripping out the Webkit ghost formatting, it wasn't in Chrome but at some point was folded back in, useless spans with Apple class names, its weird, I don't know why they're there, but they're annoying to have in my database.
   
3. This is more of a conceptual feature than actually useful. I've done some stuff with websocket, and the thought I had at the outset with bleedwrite is that it'd be cool to build it to stream out what I'm writing in real time, if you were on the page while I was typing you see my revisions Google Wave style, it wouldn't be cached, just streamed as it happened.
