Here is a little experiment (that was hanging in my drafts for some months already) with static method, static code block, [Mixin] and class constructor. Can you guess correct order of trace()s dispatched by using the following Item class? Notice [Mixin] will only be understood and init() called with flex application.
EmbedCode class generates html code for your .swf files. You can define url, size, parameters, flashVars and the result is valid standard (<object>, <params>, <embed>) html code, that you can just copy paste into your htmls, blogs, gigya widgets etc.
