Stereoscopy Day 2026

 

Now, even more stereo!

 

June 21st is "Stereoscopy Day".  On that day in 1838, Sir Charles Wheatstone presented his reflecting stereoscope to the Royal Society of London and demonstrated his theory of binocular vision.  More info about this event, the fifth, is at the Stereoscopy Day site https://stereoscopyday.wordpress.com/ or #StereoscopyDay 

 

Let's start the celebration right now!   Presented is a relaxed view 3d stereogram of clouds at different levels:

You can view my 3d / stereogram / stereograph / stereoscopic images by selecting one of these labels.  These links each should produce the same image results, as I have been pretty good about labeling:

Security envelope basket woven

 

Five bars per band

 

The basket weave pattern used for this security envelope is very rustic.  The pattern does take a break at the fold line.

 

 

Spathe and spadix

 

Pulpit and Jack

 

A close-up view of a Jack in the Pulpit.  From its colors and striping, this may be the Arisaema triphyllum.  The spathe (the "pulpit") surrounds the spadix (the "Jack"). As the fruit ripens, the red berries appear.

The Scovill Brass Company started in 1802 in Watertown, Connecticut.  It acquired the Oakville Manufacturing Company of Oakville, Connecticut in December, 1923, making it a division of Scovill.  That division was closed in 1973.  The Scovill Company went through some business tribulations; in 2014 it became Morito Scovill Americas.

 

The chronological order of the packets is not certain; they are shown in the order they were found.

 

Some good advice

Some good advice here!

This flyer offers some helpful advice:

 

DO NOT DUMP

INTO TOWER

 FLOOR STACK.

 

PUT IN-LINE

  WITH OFFICE. 

 

That sounds like good advice - for someone.  But who? And about what?

 

The numbers in the lower right corner ( 34-2002-9438-6  0264914.1 ) do not provide relief.

 

 

Security envelope polygons 2

Unlike the polygon security envelope pattern previously posted here,

 

Blue polygons

 

this polygon pattern does not seem to want to be mirrored and matched to create a bigger pattern.  Despite that hinderance, it is an interesting pattern.  

 

N.B. this pattern came from an envelope used by the same business that used the previously posted polygon pattern.

 

Addendum:  by doing a V flip and an overlay, it is possible to extend the pattern slightly in the vertical; nothing seems to inspire a further extension in the horizontal or vertical.

 

 

Just a flip and overlay

 

Maybe one of the readers can provide a way to extend this pattern?

Somebody else's sunset

 

Golden glow in the west

 

Somebody else's photo, of some place else's sunset, is their idea of a sunset.  It seems to be, but need not be, a vision from the past.
