In my 30 days trial with Flex2 I decied to make all the tests I can in order to learn as much as possible.
After making my first component I thought at doing something more interesting and much similar to a web application. So I first downloaded the ActionScript 3 libraries developed by the Adobe labs, then I activated an application key with Flickr.
I had to modify something in the flickr actionscript libraries and add some new classes for my experiment (adding for example the do your homework now Comments and http://www.papilouve.com/argumentative-essays-on-smoking/ Interestingness class, currently missing in the adobe libraries), read the documentation of the Flickr API, but at the end I managed to build a first test: a Flash web-based Flickr browser.
