I just released a Windows XP/Vista (I develop under Vista) called HD Panorama.
It can be downloaded from www.lightboxeditor.com/hdpanorama/hdpanorama.zip
and is a 3.0 meg download.
It rotates beautiful and artistic High-definition (any resolution) panoramas on your desktop using some new algorithms created just to display VR panorama moving gently and slowly
The panoramas are all high-definition and beautiful pictures from around the world, VR corrected fluidly on each frame, making it feel much more like you are there.
The technology has been described as "must be seen to be believed" by Michael Fereday of Gadgetspeak. He also called it "relaxing visual therapy" in a review for a product using some of the same panoramas.
It's in beta and is currently free.
the homepage is at HD Panorama Project
A link to a demo in HD (1280x720) is at YouTube - NASA Mars Rover High-definition 360 Video (Lion King)
(press 'HD' to see it at 1280x720 -- this video doesn't do it justice, as it is lower resolution than the product offers, and Youtube causes all HD video to hesitate and jerk, but it's a start)
HD Panorama runs as a standalone program or you can use it as a screensaver -- it does not install or leave anything on your system. You can just delete the directory to remove it entirely. It has been throroughly tested and is robust.
I want to use it to showcase the talent of those who make panoramas and to display them artistically (as opposed to the virtual tour method), and will be adding more panoramas. Your feedback on the program would be greatly appreciated.
