They did a great job with this, but it's also a good exercise that other people should try. These days, a lot of development styles ask you to be able to scope your work to the available time (agile, getting real, any crunch time situation).<p>I did a couple two day solo versions of this and it's paid off repeatedly. My goal was to create and launch a website in two days. Usually I went in with an idea, but all the work needed to fit into two business days. The best thing I created was probably IHeartQuotes, a web front-end for Unix fortune files.
