Like Panoramic? Try Microsoft ICE
Tried the panoramic photo stitching in Live Photo Gallery, but found it a bit basic? Try Microsoft Image Composition Engine (ICE).

ICE is a project out of Microsoft Research; outputs to TIFF, JPEG, PNG, Layered PSDs, HD View Tileset (another MSR project), Silverlight/Deep Zoom Tileset, BMP or HDI.
update: Going from the HDView blog, this builds on the stitching technology already released in Live Photo Gallery and Deep Zoom Composer, by adding multiple output formats, GPU acceleration, 360° blending and more. It wouldn’t be too suprising to see this make its way into Live Photo Gallery in the future.
Windows only, requires .NET 2.0, and has x86 and x64 variants, oh and totally free.
