Hi, I'm Peter! (they/them) I do all sorts of experiments with math, art, music and programming. I value human creativity; nothing I make uses AI Website: https://ptrgags.dev

Eight cross stitch and blackwork embroidery patches. All 50x70 squares (except the bottom right one we don't talk about that...) The fabric is not all the same count, but the largest plastic canvas one would fit in a 4x6 inch rectangle
Video of Screen Scrambler in action - the scene has a number of colored circles of different sizes moving around in random directions. A cursor randomly scans across the screen, picking up a chunk of pixels, moving them, and pasting them somewhere else. This repeats forever
Index card that shows the prompt I made for myself. On the left, pen colors. A=blue, B=magenta, C=black On the right, the layout. Three squares marked C/A, A/B, B/C. Lines connect the three squares of the layout together (with some arrows on the ends to indicate looping)
An abstract doodle where the patterns spill across three cards. However, the colors do something different. The first card uses black and blue ink, the second blue and magenta, the third uses pink and black
Screenshot of my Waking Hours Clock demo. It's a 24 hour clock dial (with just an hour hand). It is divided into two portions. a large orange arc for waking hours, and a smaller purple arc for sleeping hours. There are white numbers outside the circle from 0 (midnight) to 23 (11:00 PM). Another set of blue fractions inside the circle indicate proportions of daytime/nighttime.
Diagram of parastichies from your previous post with annotations. Another pink warped square is drawn inside the hole The blue circles indicate the tile corner
Screenshot of the Infinite Sunflower animation linked above. It's a stylized spiral of petal shapes, colored in yellow, orange and brown like a sunflower.

Image results for Stentor. It has a long narrow body with a flared end like a trumpet
A pixel art animation of a 4x4x4 cube in isometric view. cubes are removed one layer at a time, starting at the corner nearest the viewer. once it reaches the far corner, the animation reverses and now the cube is reconstructed a layer at a time.
Screenshot of the Pixel Maze demo on my website. A blue creature with a big googly eye walks around a maze of purple rooms
Diagram showing all 16 Wang tiles, the equivalence relation, the quotient set (one representative from each equivalence class) and then the stylized version used for designing the stamps
The set of 6 rubber stamps and a gouge
Block print of a tabletop dungeon maze printed using a handful of small linocut stamps for the different room/hallway types
Another print of the shrimp, this time with long light blue hair drawn on the shrimp a la Hatsune Miku. It's a reference to Shrimp Miku by justan oval
A linocut print of a cartoon shrimp with a big googly eye. On the right, the stamp itself, positioned to be a mirror image of the print
Two prints. On the left, a white on black print of a braid repeated several times at a diagonal on an index card On the right, a white on black print reminiscent of the veins of a leaf, though the small veins are a bit more grid like. Above each card is the block I carved
Same thing but with a music note shaped earring placed next to the googly-eyed character so now they're singing!
Blackwork embroidery project from a recent post of mine but with two googly eyes overlaid. It turns the geode into an open mouth
Picture of the cover of Life Isn't Binary
Close up of the lower portion of the embroidery. You can see some of the white and yellow stitches go over the original black outline.
The finished blackwork embroidery project. It's an abstract doodle on a square grid. The floss colors are black, purple, white and yellow, i.e. the colors of the nonbinary pride flag. The bottom middle panel looks like an agate geode
The same embroidery, now with more detail in yellow stitches. There's still a few areas yet to be filled in
A pair of bookmarks. One is a Progress Pride flag, the other is also a Progress flag but with squiggly, stylized lines. Above it, a bunch of watercolor brush pens used in the making of the bookmarks.
Earlier photo of the embroidery pattern with only black, purple and white lines. The translucent plastic canvas adds a bit of grey to the background
Close-up of the plaid section, showing how the criss-crossed stitches are in the order black, purple, white, yellow, as in the nonbinary flag
Same abstract embroidery pattern, now with yellow stitches added to the plaid region in the middle
A cross-stitched Progress Pride flag
The same embroidery project, now with further details stitched in white (on top of existing black and purple stitches)
Rough 2-panel comic loosely following the dialogue in the previous reply
Same embroidery project, but now the 7 irregular polygons are filled in with various patterns in purple thread
A rectangle broken up into irregular polygons in black thread on translucent plastic canvas
Abstract doodle reminiscent of two cross section of underground tunnels. The top one is in mint green, the bottom in orange. This is an ink wash, so I used a water brush and smeared the colors. I outlined the result with fineliner once it dried
Abstract doodle of a blob with contours that make it have a sharp ridge Above it, some fountain pens
A lego snail carrying some mail. It's perched around some succulent plants
Bookmark I'm using as a new cover photo. Above it, a pile of brush pens and sharpies.
A circle, three s-curves, and a c-shaped curve, forming the common features of my monogram
Three cards, each with my monogram PG drawn in a different style
Dense ball of crochet stitches, making a fractal-looking shape. It's reminiscent of the folds of a brain
L-system with left context equivalent to the original pattern from the video. Below it, some diagrams of an example starting from the string "wbbwbb"
Diagram of values for n=2k + 1 Some patterns have the form of a sequence of numbers, followed by the same sequence negated When k is a power of 2, you get powers of 2 followed by their negations (when plotted on a circle it looks vaguely like a lopsided hourglass)
Table of the first several powers of 2 modulo n. Each column is eventually periodic. There isn't a clear overarching pattern, but there are several partial patterns if you look closely
Table of x modulo 3 in binary for 0 through 7
Screenshot of grayscale gradient bitwise-XOR gradient
A doodle of a choir of ghosts, singing a spooky minor major chord (EbmM7) Above it, the fineliners and brush pens used to draw it.
Abstract geometric doodle of a pile of shapes in blue, purple and orange. Above the drawing, the fineliners and brush pens used to make the drawing.
A different card depicting a sob emoji face crying a pool of tears. A thought bubble reads "feeling angry is so scary!"
The shreds of the old card, dipped in water to make pulp.
The card further destroyed by hole punching
The same card, cut up with wavy scissors
Drawing of the text "AI" on a card with pens above it. The AI is colored in a disgusting combination of many colors, representing AI slop Above the letters, grey smokestacks and a purple cloud with skull and crossbones. This represents both the literal pollution by AI datacenters and the figurative pollution of countless areas of human life (work, education, art, the list goes on)
Doodle of a snake carrying a backpack through the desert. The snake extends its tongue towards the stars and takes a deep sniff
Abstract doodle of layered shapes. Lines in Salmon pink and grey fountain pen

Fifth page of the doodle breakdown that shows how the two types of symmetry in the diamonds combine to reveal additional symmetries
First page of the doodle breakdown, showing the recursive symmetry of the L-shapes
A doodle of recursive patterns. The overall structure is a set of L-shapes nested inside each other as you go from the bottom left to the top right. In each L shape, at the top there's a circle with one quarter colored in. The circle rotates a quarter turn clockwise each iteration. In the bottom left, there's a creature that's mostly a big eye stalk with some other embellishments like stripes. From iteration to the next, there are fewer stripes. In the bottom of the L, there is a sequence of diamonds with a circle in the middle. As you go from left to right, it alternates between filling in the diamond vs filling in the circle. In each successive iteration, the whole row of diamonds is repeated but with the fill style swapped. And finally, from one iteration to the next, I toggle between two pen colors (purple to dark blue and vice-versa).

Screenshot from the fractal animation. it's a number of cartoon vortex shapes in mint green and red arranged in a fractal pattern
