These are beautiful. There’s no shortage of excellent coders in the open source/free software world, but we desperately need more technical writers, designers, and artists.
(Which is not to say that the coders aren’t valuable, obviously.)
What license are these available under? It doesn’t seem to say anywhere, and the download doesn’t contain a file specifying it either. At the bottom of the page it says “Creative Commons”, but which CC license specifically?
Just asked him on twitter, looks like it’s BY-SA 4.0 but the actual site hasn’t been updated yet to reflect that.
