One of the things I wanted to do for a long time was create a pluggable "flow panel" - kinda like for housing cover flow and like layouts. Well, over the weekend I created one, with full virtualization and pluggable logic to add various type of flow effects. Below, are some screenshots of the panel in action:
This demo showcases the flow panel using Bing.com's homepage backgrounds. The demo currently is limited to a single flow effect, which is based on my earlier effort - however, because it is virtualized it uses a quarter of the memory whilst featuring much more complex UI and effects. Going forward, I'll put the project on Codeplex, under the title nFlow - it will also house various flow effects in addition to the panel itself.
Have a look at the Bing Gallery, here (requires Silverlight 3).
Update: FYI, this demo app keeps upto date with all the daily homepage images from Bing.com, and the listing goes back till mid July 2009.
