As we have now access to archived OSIRIS images and data from other instruments, I think that it's good idea to start up special topic for that.
Here are few results from the newly published data: Hi-Res crosseye stereo color image of Imhotep regio at resolution 0.5 m/pix. Anaglyph version: Global color image at 2.2 m/pix: -------------------- |

I took the 30 frames from W20140910T035912757ID30F18.IMG through W20140910T042812710ID30F18.IMG and made a full HD bounce animation of the slow rotation. A tiny preview version is included below.
(Click for 1920x1080) It's hugenormous (65 MB), so beware; it may take a while to fully load, but it's one of the est things I've seen from Rosetta. The images were processed to show the area of the neck and connected regions that are in shadow. The frames were all captured 1 minute apart by the wide-angle camera, but are being played at ~15 frames per second. The 1920x1080 dimensions were achieved by cropping the original 2048x2048 frames, not scaling, so this is still at the native/original resolution. |

It uses a bit more up-to-date animation format: http://i.imgur.com/IJnKFMz.gifv Thanks for the animation Herobrine! -------------------- Antti Kuosmanen

Use the following link with gifv animation automatically generated by imgur for faster loads. It uses a bit more up-to-date animation format: http://i.imgur.com/IJnKFMz.gifv Thanks for the animation Herobrine! imgur's "gifv" format is just a web page that serves either a .gif file, a .webm file, or a .mp4 file. In this case it's serving a lossy .webm file, displayed in an HTML5 <video> element with the "loop" and "autoplay" attributes set. imgur prefers to serve the lossy video formats for large, photographic animations because the file size is usually much smaller and saves them a lot of bandwidth. The GIF file I linked is the original, lossless (relative to the 8-bit result of my processing) version. The WebM video in your link is lossy compressed, so it is noticeably lower in quality, but still very , and clocking in at less than 2% the file size of the GIF, it may be a better option to anyone for whom bandwidth is a concern. The quality difference isn't a big deal with respect to aesthetic enjoyment, but it can make a difference, for example, if you're trying to find free-floating rocks (not sure what we're calling those, actually). The rock I pointed out a few posts back is visible in the WebM version too, but this fainter one I noticed later is only barely detectable in a few frames of the .WebM version as a smudge, but in the GIF version, a crop of which is seen below, the rock can be spotted in every frame (though very faint), as it moves from the bottom-left to the top-right, and back.
