Hi. I attended the Silverlight demo last week and it blew me away. Very impressive stuff. Here's a Silverlight control you may wish to develop:

r.a.d. slideshow: Enable users to put together images, text, and animation using the easy-to-use design time controls that Telerik does so well. For example, users could do product demos and tutorials using this control, stitching together screen captures along with audio and mouse movements, screen transitions, and ability to export to PPTX/PDF formats.

Users could select the images and enter the text for each slide and choose animation for objects.
