regular hexagon pattern #2541
 Grid  CC 0

The image depicts a pattern of regular hexagon.As I made to use it for myself,I want to others to use it.Speaking about the ratio of the image, height : width = 2 : √3(1.732...)Ridiculous to say,I realized later that this image is not honey comb pattern.I have to slide the second row.

Not strictly seamless in that opposite edges are not identical. But they do marry up to make an interesting pattern

The name alone is awesome, but so is this sweet dark pattern.
