Some of you know my obsession with Lean, Agile, and ToC.  Ideas are everywhere.  Idea is nothing. Execution is everything.

In that vein, one of my No Fluff, Just Stuff talks is called "The 90 Minute Startup".  In it, I build a real, live dotcom site during the session. You can't get a much shorter time-to-market than 90 minutes, and I really like that.

In case you're curious, I do it through the use of Amazon's EC2 and S3 services. 

The app I've used for the past couple of sessions is a quick and dirty GWT app that implements a Net Promoter Score survey about the show itself. It has a little bit of AJAX-y stuff to it, since GWT makes that really, really simple. On the other hand, it's not all that exciting as an application. It certainly doesn't make anyone sit up and go "Wow!"

So, anyone want to offer up a suggestion for a "Wow!" app they'd like to see built and deployed in 90 minutes or less?  Since this is for a talk, it should be about the size of one user story. I doubt I'll be taking live requests from the audience during the show, but I'm happy to take suggestions here in the comments.

(Please note: thanks to the pervasive evil of blog comment spam, I moderate all comments here. If you want to make a suggestion, but don't want it published, just make a note of that in the comment.)
