Today’s web sites need to provide more information than ever to the end user effectively and quickly. A great way to do that is to offer engaging interactive experiences like this energy savings calculator which presents a somewhat complex subject matter and distills it to an easy to grasp concept. It shows in real-time how a number of variables interact with each other as you move the efficiency bar from right to left. This model can be used for many other applications such as illustrating changes over time, animating objects to explain how things work, or configuring a complex form with a unique graphical interface. Responsive break points and compatibility with phones, tablets, and browsers are additional benefits.
