It is colorful, but it is not a rainbow

Colorful cobbles

 
cobbled street with manhole cover and drain grate
Rain drain

This scene in the street beneath our feet has an 8 x 3 rectangular opening storm drain grate and a 9 by 9 square diamond manhole cover with 23 "teeth".  The somewhat symmetric cracks and colorful cobbles add to the scene.
 
Other examples of that style of manhole cover can be seen here and here.

Security envelope polygons

Security envelope patterns come in different patterns.  Usually, they are small and tightly packed, covering the whole interior of the envelope to obfuscate the contents.  It was a pleasant surprise to receive this envelope security pattern of widely spaced polygons.

It's a tee shirt!

This blue polygon pattern has been mirrored left-right and  up-down.  The tiny diamond in the center is the lower-right, lower-left, upper-right, and upper-left corner, respectively, of the pattern after the horizontal and vertical flipping and tiling.

Some sketchy V and H flips and overlays give a rough draft view of a more complete polygon security pattern.

It is possible to continue the process and create even denser patterns.
