Symmetrical mirror tessellation tile that looks vaguely like a dragon (or at least a horned creature with wings and a tail) from the right rotation.

Four sided symmetrical mirror tessellation tiles are created by mirroring and and reversing an original side.  

• Define the a path for the first side (s1).  
• The second side (s2) is a mirror of side s1.
• The third side (s3) is the reverse mirror of s1.
• The fourth side (s4) is the reverse mirror of s2.

The result is symmetric about both of the diagonals.
