Well not exactly a URLVariables replacement, but I often use the URLVariables.decode() function and find that its very picky... like if there is an extra & or something it freaks out and breaks, or if there are line returns. As a quick and simple solution the other day I wrote this function into part of a class (Model class) that I was working on. Fixed the problem and even handles Spanish characters nicely.
There is plenty of room for improvement with this simple function... feel free to post improvements in the comments.

This is a simple idea I had awhile back... This snippet searches twitter for the #asgraph hashtag and if it finds standard Graphics class method calls it renders them.
So if you tweet something likethis :
#asgraph beginFill(0xFF); drawCircle(200,200,10);
it will get rendered into the below swf (you'll need to refresh to see your tweet get rendered):
This movie requires Flash Player 9
Here is a direct link to the swf

This contest entry by Kyle Phillips is a utility class for dealing with google analytics. If you haven't messed with google analytics I suggest you give it a try.

I usually find myself adding google analytics code in a very hacky way... usually because the client asks for it at the 11th hour. Using a class like Kyle's would enable you to simply add the tracking code from the start and then if the client doesn't ask for it... you can just keep the class disabled... or charge more when you offer google analytics tracking for "phase 2" of the project

Found myself writing this snippet today.... it figures out if the current swf is inside a container (Loader) or not... lots of other ways to do this... feel free to post your version in the comments...
