How to Make Your Own Tessellation: Flipping
If you compare the two pictures you can see the differences. In the original, on the left, all the calves are looking in the same direction, their left.
In the picture using flipped lines, on the right, half look to the left and the other half to their right! The two sets are mirror images of each other.
Look at the construction lines too. They form equilateral triangles but the arrangement is not the same.
This is why some tessellations, like 'Progressive Hope', 'Clowns', and 'Foreign Legion', have motifs facing both ways and upside down too.
