Some tech specs: 717 Gigapixels in a 5.6 TB image: 8439 individual images, taken with a 100 megapixel Hasselblad H6D 400 MS camera. The distance between two pixels is 5 micrometer. The museum writes the images were stitched together "using artificial intelligence".

I analyzed two years' worth of data, consisting of over 1 million solved puzzles. This included puzzles solved "against the clock", of three different sizes. For each size, Chrome users were the fastest solvers, Firefox users came second, and IE users were the slowest. The number of abandoned puzzles (started but never finished) was also significantly higher for IE users. Analysis shows that the differences are statistically significant: in other words, they did not happen by chance.

I put up more details and some graphs, and also wrote a paper about it.
