Hi there,  
Came across this nifty background effect here [http://www.helicemusic.com/](http://www.helicemusic.com/)  
i’m asuming the background that moves is under a mask that is the size of the stage, and the stage size is scaled using AS depending on screen size/resolution as on larger screens when you scale it more background appears. Am i anywhere close (very debateable!), and heading in the right direction?

If not, any ideas on the best way to achieve this?

Cheers guys,

Pat
