The Horned Lizard IV- Now You See Him; Now You Don't

I have made many different types of lizard tessellations over many years. The motif on my web header is a P6 (Polya) of a horned lizard. The tessellation  has effectively six lizards packed into a hexagon or three half lizards in an equilateral triangle. Its very stylized but is generally similar to the shape of a horned lizard or horned toad. I was always fascinated by these creatures and their pointy spines around their head and the fact that it has excellent camouflage and a really unusual defense mechanism; the ability to squirt blood from its eyes to scare off predators.  I think also I remember the cartoon character Yosemite Sam using the phrase "great horny toads" when I was watching cartoons growing up. Overall it wasn't really a scary lizard at all but more of a desert oddity that could disappear into its surroundings. So that's what this drawing is all about the ability to appear and disappear into ones surroundings. Figure 1 below is Horned Lizard IV (2017).
