Video of a series of jellyfish swimming in a trance-like motion. They appear to swim through invisible water like flowing draped cloth in a gentle breeze. Most of the jellyfish have soft, bulbous bells that undulate gently while a frilly, lacy set of tendrils flutter in sync with the undulations. A few of the jellies appear tiny–almost microscopic–and transparent, making them almost appear like an animated diagram instead of a living creature. The jellies are all filmed against dark backgrounds, bringing clear focus to their movement through space. The jellies themselves are warm, bright tones and almost appear to give off their own light as to illuminate the space by their very presence.
An arrangement of warm brown-orange jellyfish on a dark backdrop that has a similarity to a renaissance painting of action. There are 32 jellies in full view, many swimming in a downward direction, though several are pointed in other varying directions. There is no central focus or grouping. Instead, the mass of jellies appear to be chaotic while frozen in place. These jellies have some tendrils that are frilly, lacy, and bright emanating from the center of each bell, but also a series of thin, wispy threadlike tendrils from around each crown.

A user interface that is composed of a navigation section across the top, and on the lower left is a text editor, and on the lower right is a rendered copy of the story. The text editor shows a section of YAML, primarily composed of a "variables" object and a "chapters" array. The visible section of the rendered story reads: Chapter 1 A story about Blob What color is Blob? Heading: Question BLOB_COLOR Buttons for red, black, "breen," yellow, and white Chapter 2 *BRR BRR BRR* A gelatinous white protrusion slithers from under the sheet. *SMACK* Slowly, a viscous white slime overtakes the blanket and rises, as if to sit up. Two orbs slowly float toward the top of the slime and a gap forms beneath them indicating a yawn. Blob gets out of bed and pauses–a gurgling gas bubble wriggles in the slime. What is Blob thinking about? Heading: Variables at end of chapter

Obsidian's graph view showing a circular arrangement of dots with lines strewn from point to point. There are obvious large clusters of points and a thin ring of points around the outside of the arrangement indicating a less-connected periphery. Different colors are used to indicate Bibliography, People, Organizations, Zettelkasten, Journal, and Components

A detailed engineering diagram of a single chain link. Each link is 10.5mm tall, 31.5mm long, and 16.8mm wide. The diagram highlights the the chamfered pin and its through hole and through holes for zip ties in the base of link. Another callout indicates the link is constrained to a total of 120° of rotation around its pin. The link is designed to fit the width of a 10mm LED strip.

[Video with no sound] Demonstration of "Blink" game with 20 rectangles of various sizes in 4 shades of gray scattered about the screen. Many of them are pulsing or jittering erratically. After an odd period, the screen "blinks" to black for only a moment, but one of the rectangles that was not moving before is now moving. The player moves the cursor around while looking for the changed rectangle. A progress bar along the bottom indicates how far along the game has progressed. A meter in the top corner indicates how many "anomalies" are active. The player's cursor moves around frantically, trying to find the changes. The screen blinks, a rectangle starts moving, the meter ticks upward. The cycle repeats a total of 5 times. Eventually, the meter changes to a warm orange indicating imminent failure. Another blink happens. Another formerly-static rectangle moves. The player fails to click at least one of the anomalies. A prompt appears saying "Too many anomalies! You lose." The playe
