This post of Antoni Dol is dedicated to QuoteFloat - an animation for TextBlock elements, inspired by the way the HTC Touch HD shows SMS Text messages.
It moves the text up and rotates it at the same time resulting in a spiraling effect. It is done by giving the TextBlock elements a PlaneProjection each and animating the RotationY and GlobalOffsetY properties.
The TextBlock elements are positioned below the bottom of the Canvas. The Canvas has a Clipping Mask so no one will see them until the animation starts.
