These two tessellations are from the same D4 symmetry group however they differ in that the four color version in Figure 1 has interlocking birds flying in circles. Figure 2 depicts an enlarged version showing the interlocking rotations. The figures are similar to M.C. Escher's No. 118. The "star" comes from the eight birds that surround a central point (four heads, four tails)and the D4 overlaps. The second tessellation or tiling is black and white. I have taken the same symmetry group and combined a jet and a bird motif. These two images look very different but are very much related.
