[Antreas P. Hatzipolakis]:
Let ABC be a triangle and L1,L2,L3 three parallel lines through ABC.
The reflections of L1,L2,L3 in BC,CA,AB bound a triangle A'B'C'.
As the lines L1,L2,L3 move around A,B,C being parallel, the
NPC centers, orthocenters and all same points on the Euler lines
move on fixed circles, whose the centers are collinear.
