More Black and White Tessellations

The images below are of two tessellations designs I have had for a number of years. The frog tessellation dates back to 2001 an the bird tessellation dates back to 2006. The black and white images are visually very appealing and crisp. Figure 1 is Frogs. Figure 2 is Birds V.
