I designed, art directed and built this campaign for the games channel at blueyonder, there were 40 different banners all needing to be turned around every week, from Flash and animated GIFs. The challenge was one of file size since they wanted to show a lot of the games, but there was a real limit to what was possible in a 10/15/30K file.
(P.S. There should be 5 adverts visible – if not and you’re running an adblocker (U-block, ABP etc) please disable it and refresh the page.)
I created several rounds of mockups, you can see some of the original artwork here, you can get a sense of the design process from these.
