[vbasnscg] Summoning Eulerian spirits

The pentagram inscribed in a circle, classically drawn on the floor to summon spirits from alternate planes of existence, is an Eulerian graph: it can be drawn without lifting a pencil off the paper.  This suggests interesting ways to draw the figure, for example, with a single strand of EL wire or inflammable rope.

The pentagram requires 60.2% of the rope; the circumference of the circle uses up the remaining 39.8%.
