I see this done in a number of places, commercials, websites etc and have always wondered how it’s done.
For example: http://www.northkingdom.com/
The vines/flowers being revealed/growing in the top right. How is that done? Is it as simple as an animated mask? Or is this something done in After Effects and brought into Flash?
Any help is greatly appreciated. I’ve tried searching for it but don’t really know what it’s called unfortunately.
