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.

This rough sketch demonstrates the result of enthusiastic polygon pattern and line matching.

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

 

Budd and buddy

 

"Stripey" and "Red"

Seldom scene

 

Red door (sunlit)

 

This red door at the back of the building is seldom seen.  This scene is of more interest than what is seen at the front of the building.

 

 

 

Frozen fog

 

one hundred millimeters high

A snow fall of frozen fog in still air left four inch "sugar piles" sticking to the tree branches.

 

Bare to the walls

 

Nothing left behind

With the closure of a store, the interior was gutted to the bare walls, leaving behind an empty storefront. 

 

Most of the items on the outside back wall were also removed. 

 

Red sign left behind

The red "Video Recording In Progress" sign was left behind, reminding the casual passerby that video recordings are in progress.

 

 

Empty 3d interior

Cover relic

 

Is that an eye?

  

This "Time Warner Cable Of New York City" manhole cover was made the East Jordan Iron Works.  In 2016, Time Warner Cable was acquired by Charter Communications, which brands itself as "Spectrum".  Despite its re-branding, the parent company still has not made a complete logo consolidation of its acquisitions, leaving these relics in the street beneath our feet.
