Zoomable raster world map (which happens to be using Stamen’s Map Stack).
Apparently I broke it by trying a projection other than the original. :(
Based off Calvin Metcalf’s version, which in turn is based off Jason Davies map which is a combination of Mike Bostock’s raster reprojection, automatic projection tiles and a MapBox terrain example.
Thanks to Mike Bostock and Nelson Minar for their comments and encouragement! And Obviously Jason Davies for making the original.
