Well I really wouldn't have wanted to do it by hand. But, actually,
if you look closely, you will see that in the original the waviness
of all branches is about equal, while in the render, the amplitudes
differs in some places. I *think* this is caused by the differing
distances due to the depth of the tree, which might mean that
Escher did not really design the tree itself in 3D ... but his
manually drawn tree gives the image a much nicer composition
than the n-th random branches I finally decided to go with ;)
