This appears to be a real wall behind him, and I can’t understand how it is structurally sound. It looks like a fault went through the brick wall.
Screenshot of a man on television. Behind him is a brick wall with the lowest layers of brick horizontal, and the upper layers of brick laid on a 30 degree angle.

I can assume the sale of RFID protection clothing for pregnant people is in response to this idea that pregnant people provide free wifi.
Clip from Amazon website of a tank top that provides Faraday protection shield to fetus, nothing it can block electromagnetic radiation from appliances Sign from a row of seats indicating priority seating for disabled, people with infants, and a pregnant person that has the arch symbol normally associated with wifi coming off the torso.

I’ve gotten to the point where I can’t watch much news anymore. This is an anxiety attack.
A television labeled news mix with six different news channels in small tiles next to each other filling the screen.

Very important to note: Darth Vader is a grotesque not a gargoyle
Photo of a sign on a fence with a photo of the Darth Vader sculpture on Washington National Cathedral. Sign says: gargoyle or grotesque? Darth Vader is a grotesque, not a gargoyle! Like gargoyles, grotesques carry rain water away from the building’s walls. Gargoyles are essentially rain pipes that move water via pipes or channels, usually through the mouth. On a grotesque carving, rainwater runs off a prominent feature, such as an ear or nose - or I. Darth Vader’s case, a helmet.

I stitched an octopus riding a shark, as I was inspired by the recent video footage. #sciart
A dark blue piece of fabric with gray fabric in the shape of a shark on top. Black thread was used to depict the sharks's gills and eye. On top of the shark is brown fabric with brown thread roughly in the shape of an octopus with four arms hanging down.

There are certain people I really enjoy seeing on tv because of their background. Ben Wikler is one because that cow is everything.
Screenshot of a man in suit and tv being interviewed and in the background is a painting of a friendly looking cow.

A friend shared this on FB. I looked at the figure before reading, and the first thing I thought was, the lower one is how the gel electrophoresis should look. The upper one is how mine would look. #nerd

I am making a bunch of snowflakes for a crafting project. This is my chemistry nerd snowflake showing the crystalline structure of ice and hydrogen bonding.
A hexagon shaped piece of fabric decorated with beads. The beads are arranged in a hexagonal pattern. Large light teal-colored pearly glass beads represent oxygen and are the points of hexagons and are next to smaller white pearly glass bead which represent covalent bonds. The white beads are next to dark teal-colored beads, which are smaller than the large light teal beads and represent hydrogen. The hydrogen beads are next to two tiny white pearly beads that connect to the oxygen beads and represent hydrogen bonds. The hydrogen beads, covalent bonds, and hydrogen bond beads form the sides of the hexagons.

"You'll be visited by three spirits"

The three spirits #cats
Photo looking sideways at three steps inside a house. On each step is a cat looking down at the photographer. The first cat is a long haired tortoise color, and the other two cats are black and brown tabby cats. All three cats have a typical judgmental look.

I am not sure what kind of bird this is, but it is one of my favorite photos of a bird I have ever taken. Bird was on Barro Colorado Island in the Panama Canal and interested in what us tourists were doing.
Photos of a bird sitting on a tree brach looking down at the photographer. Green leaves are above the bird in the background. Bird has a large, round, white belly, and a blue-gray head with an orange beak.

The triple point diagram of states of matter. Temperature is on the x-axis, and pressure is on the y-axis. A curved line starts at the origin and runs somewhat diagonally. Vapor is below the line, solid is between the y-axis and the triple point, liquid is above the line and to the right of solid.

The entrance to the express lanes of this HEB (Texas grocery store) has wires scored in the floor that is definitely the same type as used in streets to determine if there is a car waiting for a light.
Photo of a concrete floor with a rectangle scored into it. Rectangle is about five feet by two feet.

Drafting tools from engineering school like 30, 60 triangle comes in handy when making proper fabric snowflakes. Because improper 8-sided fake snowflakes are all kinds of wrong.

I no longer subscribe to WaPo, so I can’t read details, but this a fascinatingly hilarious headline.
Washington Post headline that reads “Virginia Gov. Glenn Youngkin claimed Jordanians ‘crashed’ Quantico. Feds say it was an Amazon delivery.”

Long before there was the Waffle House Index, there evidently the Sneaker Index.
Museum poster that read: Preacher for the Patuxent I’ve never allowed myself to be discouraged. As Winston Churchill says, I will never, never govern up. - Senator Bernie Fowler 1988, Senator Bernie Fowler held the first wade-in. A lifelong resident of Calvert County, he was concerned about water quality. He waded into the Patuxent River to see how deep he could go before losing sight of his white sneakers. This became known as the “Sneaker Index.” The wade-in has evolved into a symbol of the need for stewardship of the state’s precious water resources. Poster has a bar chart called wade-in vs. turbidity showing Turbidity through the years versus the sneaker index.

This painting is making me laugh unbelievably hard. I don’t even think it is great technically, but it’s just silly.
Painting names “Grazing Sheep” by Robert Kyle. The foreground is green with white sheep grazing. The middle ground is brown with several black profiles of dinosaurs. The background is blue sky with a flying dinosaur. The painting is rather simplistic technique.

I can’t decide if these look more like flowers or gears. Now I thinking of stitching flowers that work like gears.
Three pieces of art. Each are made of paper folded within itself to make loops. The loops are put together to form a circle. Numerous circles are on each pice of art.
