LIGHTNING BOLTS by Melina

Like Wyatt's pyramid tessellation, Melina's lightning bolts are probably best viewed as abstract / geometric / alhambra style tessellations, though we can also see this picture as an Escher style (representational) tessellation of lightning bolts.

This is, of course, a translational (slide) tessellation like Wyatt's pyramid tessellation and all the other tessellations which appear before Melina's in this gallery. It has neat, organized lines with uniform spacing-- as a tessellation it's technically perfect because it contains no gaps nor overlaps and its repeated lightning bolts could entirely cover an infinitely large 2D plane.
