When Research In Motion purchased the Sweden-based company The Astonishing Tribe (TAT), it purchased more than a talented group of people obsessed about advancing user interface design. It also bought TAT's technology framework, called Cascades. TAT's philosophy is that Design Loves Technology, and the Cascades development framework makes it easy for developers to put amazing animations and effects into apps.

We have had a good look at Cascades demos before, but for the BlackBerry DevCon Europe keynote TAT packaged some of them up into a high-tech Cascades Cookbook. Check out the video above to see some very cool effects in action. Cascades is being built right into the BlackBery 10 NDK, so BlackBerry developers will easily be able to bring this kind of quality to BlackBerry apps.
