So, digging into as3 portfolios, there is an enormous collection on-line worth seeing.
For a starter, here is a link to Warm Forest Flash blog site, to a post named 21 Well-Designed Flash Portfolios.

A delicatessen for those who, like me, still believe in Flash despite all the warship against it, or like learning from high-level compositions and smooth usability.

Not a waste of time for sure!
