Now that Windows Presentation Foundation is much more stable, and all it's tools are appearing in usable condition, I've started moving some of our projects to WPF.
The first of which is PixelSpread.
PixelSpread is a more-or-less ANTI-ORGANIZER. Don't let the name fool you though, it has superb auto-organization facilities. PixelSpread is made especially for designers (web and graphic). Photographers have recently gotten tools that let them organize their photos on a digital light table and work like they do in the physical world. Now that's all nice and good, but a much more simple (yet complex) solution is required for graphics designers who have literally thousands of small images (icons, graphical widgets, etc.). The thing is, designers often work with pieces of a single image. For example, take a button for example - it is (in web design especially) comprised of three different images: left side, right side, and the middle that can be stretched as wide as need be. You have to be painfully specific to organize these images so that you can see them in order in your image viewer or Windows Explorer. And organizing multiple such things is a pain. Trust me. I manage over 651k+ such images.
So, in comes PixelSpread. NOTE: This screenshot is from the WinForms .NET 2.0 prototype. This has 60% less features.
So, PixelSpread lets designers randomly drop images to keep here in a "spread". You can have more than one spread and share a single image across multiple spreads - like the new Virtual Folders in Vista. You can store a more than one format for each image. You can instantly copy from PixelSpread to your favorite web design or graphic design software.
PixelSpread maintains 32-bit transparency and supports Vector objects as well. You can zoom in/out an entire spread. Featuring state-of-the-art image compression (storage only), the PixelSpread data storage layer compressed a 291MB Corel PhotoPaint (CPT) file to 10.3MB, and a 325MB PhotoShop (PSD) file to 19MB.
With the move to WPF, the UI is more more flexible and customizable. The memory footprint is smaller, and the application is now seriously much more fun to use! 
Even with the move to WPF, PixelSpread still uses the Nukeation XCOPY™ Engine written entirely in Visual Basic 8.0 and sporting a custom back-end.

PixelSpread is intended for a Q3 2006 release. There will be a free "Express" version of it as well. Expect a beta in the coming months.
