I have spent a good chunk of the last three days playing with the data, and it's spectacular. Most cameras that have been sent to the outer solar system have detectors that are about 1000 pixels square; the OSIRIS detectors are 2048 by 2048, and breathtaking in their detail.
ESA provides a really cool browse tool that lets you get a feel for what's in the data. You can browse all of the Rosetta data from both OSIRIS science cameras and the Navcam engineering camera at this site. But, geek that I am, I want more information at a glance, so I set out to build my own browse pages to the data.
