I wrote a simple shell script[0] to scrape and output the latest image. It uses the tiles from their online satellite map[1], and can output images in increments of 1x1, 2x2, 4x4, 16x16 tiles (each tile being 550px by 550px). Here is an example with 2x2 [2] If you have any suggestions or bugfixes, feel free to fork or comment. EDIT: Also works for a single tile[3], also clarity.

Is anyone busily tapping away at a Windows port of this? I'm enthusiastic, but it would take me all day/week

  Just give it a shot, you could translate it line for line into Ruby, and use ImageMagick or something. Don't sell yourself short, it won't take as long as you think!

  You could probably run it in a cygwin shell (after installing curl and ImageMagick).

I wish there were a pair of these satellites separated by a couple thousand miles/km, so we could view these images with next-gen, hi-rez VR goggles and see the surface and cloud topography with enhanced depth.

  Let's do a sanity check on this. Cloud height is at about 60,000 feet maximum (in the tropics http://www.srh.noaa.gov/jetstream/clouds/height_max.htm http://www.srh.noaa.gov/jetstream/clouds/height_max.htm). Let's be generous and say this is 20 km maximum height. Earth's diameter is 12742 km. The clouds are about 0.15 % of this size, relatively speaking. The full images are about 11k by 11k, so we can say that 1 px is roughly 1 km. This means that the clouds will be on the scale of 20 pixels, roughly. You know what, this might actually work.

  I've always wondered if https://xkcd.com/941/ https://xkcd.com/941/ actually works and if anyone has done it yet

the max tile value is actually 20x20 (i.e http://himawari8.nict.go.jp/img/D531106/20d/550/2015/07/10/205000_19_10.png http://himawari8.nict.go.jp/img/D531106/20d/550/2015/07/10/2...) making it the 11000x11000 res.
