Mobile devices such as the iPhone provide state of the art interaction capabilities also for web browser applications. Our mobile development is targeted to a Energy Awareness application that provides playful access to detailed and realtime information on energy consumption of appliances of a household. Using the available Safari Browser that adopts W3C web standards we demonstrate the implementation of a 3D carousel giving access to cards on a web page where each card gives access to information on one appliance. The carousel can be browsed using the multitouch capability of the iPhone. We describe the programming approach and discuss the lesson learned in developing the touch interaction with the carousel.
