Holler Sydney has contributed to one of the most successful new iPad applications, Granimator. The application which is currently in the Top 10 of free apps in the UK was developed by English studio UsTwo. It lets users design wallpapers, using only their fingers. The graphics are sourced from globally recognised illustrators and creative studios such as Airside, Buro Destruct, mcbess and Jon Burgerman. Holler's contribution is the only one from Australia and was designed by Kerry Edward and accompanied by sounds from Sydney musician Eli Murray.
