How to start movieclip dynamic like this site

Hello.
How do you start movieclip dynamic?
like start a movieclip ONTOP of another on like this site…
http://www.rob3d.com/ … Does anyone have a tutorial or something like it …?

if you mean another swf… just use the loadMovie command to load it into a blank MC. There is a tutorial on this… just run a searh here at Kirupa (I suggest looking the the tut by the man himself - making a full flash site).

Peace

but doesent the clip under the “top” clip make the framerate slow down or can you make that clip go away like “unload” at the point where the top clip shows 100%?
