The Telerik Presentation Framework (TPF) allows for easy to build animations on all controls, based on it.
This example demonstrates a zooming effect of an RadElement / RadItem, placed in a BabbleBar control. The BubbleBar control is a simple layout which arranges several RadButtonElements. The scaling animation is achieved by a property setting applied to the BubbleBarElement which changes each button's ScaleTransform property to achieve the nice zooming effect.
