Part of my work at Virgin Media was the design and build of a lot of animated flash banners or GIFs depending on the requirements. These ranged from simple leaderboard and MPU units to full Page takeovers. Many of these were animated to sync up with each other and they all had a prominent CTA to get the customer engaged.
I've created similar products for other clients like The National Theatre, Lucozade and PG-Tips at Hey Human (BCL), The Economist at Polymath and Alliance Trust at Tangible.
