I am trying to do animation where is balloons floating from down to up. This is much like a popular snowflakes animation but upside down. And I have tried to convert some of them into this balloon thing that is now looking like this:
http://koti.mbnet.fi/leeko/pics/balloony.html

But there are 2 problems.
First the smaller balloons (that should be behind the bigger ones) sometimes float infront of the bigger ones.

Secondly I would like that the picture of each balloon is randomly selected from about 10 different possibilities. So there would be more variety in this thing.

Now there is loop in Layers actions witch duplicates this balloon movieclip. And in that movieclips actions has the script that makes it float etc.

Any ideas?
