macromedia flash sitedesign: Ok, check site this out...
http://www.swishzone.com/products/sites/site09/main.html

It basically is a flash site, with several "pages". When you click on a page
button the site "scrolls" right and shows the page. Kinda 'slides' the page in.

How can I recreate this?

I made a fash file that when you click a button it plays the appropriate tween
to make the page appear to scroll and slide in. Basically I would have to make
all the tweening in the timeline and use actionscript at the tweened frames to
figure out if I am supposed to stop on the frame associate with the page I want
to go to. Another complexity addition is that it slides fast and then slows
down as it approaches the page, thus adding the cool sliding effect. This could
get really rough though, any simpler ideas?

Ok, here is my attempt at recreating this. It could work but you'd have to do a
lot of work, especially if you wanted a bunch of "pages".

This effect is done completely in Actionscript and does not use tweens.
The top part of the site is a single movie clip that is slid back and
forth (underneath a mask) depending on where it needs to go.
Essentially when the user clicks on a button a user defined function
figures out how far the movie needs to be moved to the left or right.
The further the image must slide the faster it gets moved. The distance
to go and the speed at which to move is recomputed in each frame, so as
the distance gets shorter, the speed gets slower. This is what creates
the gradual speed up / slow down effect.
