In 2010 I built a set of animated Flash banners for a nonprofit called Global Nomads Group centering around a character called the Mooster, half moose, half rooster, who goes “Cock-a-doodle-moo”. These banners were developed entirely with the GreenSock tweening engine. The versions I’m showing here are in ActionScript 3, but I also converted all of them to ActionScript 2 for a few sites who would not accept AS3 ads.
This first one is the 300×250 version. Be sure to look at the other two, as they are very different designs, by clicking on the page buttons at the bottom of the post.
