I was the lead Flash developer on this project for Yell Jobs. The main page originally was going to use a Box2D physics engine but it was changed to the fish you see here. The animated bubbles and fish display the latest jobs for Yell from their jobs ATS database. The locations page was also a live data stream visualisation that I coded.
Pretty happy with the results – apparently it even won an award!
