Thank you!
The butterfly projection is nice too, however, I do like the fact that one can tile the AutaGraphy one.
Thanks for the link. Seems it is only partly vectorized.

I have a thing in my head with the Waterman butterfly projection, which has similar properties. But haven't gotten round to it yet.

It might be sufficient. Maybe I'll go for the png on wikipedia.. Thank you for the assist!
