While working on the Sentinel Landscape viewer code I realised that not only could I export a view as a .png for printing, and an .svg for plotting, but I could also adjust the 'camera' position slightly left and right to generate a stereo-pair.
A little bit of experimenting later to work out which pens worked best with cheap cardboard 3d glasses I ended up with code and a workflow that would save me all the files I need and then queue them up to be printed and plotted.
This was done first for the Patreon members and now I have a handful more for sale.
When I get a moment I'll print/plot some more, but there's only one of each landscape, although admittedly there are 10,000 landscape, so consider this a very open limited variable edition 😁
Each comes as a pair along with a pair of cheap cardboard 3d glasses, because I had to buy a box of like 100 of them.
