Math Pattern Gen is now listed on The Design Tools. I appreciate that their review includes the real constraints, not just the feature list. It’s a small browser tool for making adjustable static backgrounds and exporting SVG or PNG. thedesigntools.site/tools/math-p...

Math Pattern Gen

Math Pattern Gen is a free browser-based tool for creating abstract dot patterns from mathematical structures. Adjust the pattern and colors, then export SVG

Most of my little tools start with “I wish this existed” or “this is slightly annoying.” What’s a small tool you built for yourself that you still use?

A little sibling to Math Pattern Gen is taking shape. This time, I’m playing with simple shapes and the rules that arrange them—rotation, reflection, and tiling. Still a work in progress, but here’s a first peek at Pattern Theory Lab.

Thanks for sharing, Heather! “Pattern toy” is a lovely way to put it—I wanted it to be something you could just play with.

Thanks, Elena! I’ll try the WebGL renderer and let you know how it affects the font rendering. Great to hear the PDF exporter is moving to the new render system too—that was the main rough edge I ran into.

I hit Figma’s free MCP limit almost immediately, so I moved to a self-hosted Penpot. It’s now where Claude Code and Codex help me make slides, banners, and graphics—without extra design-tool usage limits. I wrote up the workflow and tradeoffs: mrtnusym.substack.com/p/i-hit-figm...

Six real layouts made with Math Pattern Gen. The main lesson: a pattern that looks good on its own isn’t always one that accepts type well. I wrote about crop, density, and making room for the headline. mrtnusym.substack.com/p/six-ways-i...

Six ways I used Math Pattern Gen as a background

A pattern becomes more useful when it leaves room for the thing placed on top of it.

Meet Hofun, the mascot of #PRFunho — a PR community in Japan with around 2,200 members. Its cloud-like shape represents conversations spreading gently. The eyes began as flipped P + R letterforms. I made 12 expressions too. Which one is your favorite?

I wrote a short technical note on how Math Pattern Gen actually draws patterns. The formulas don’t render lines directly. Each structure becomes { x, y, r }, then thousands of dots do the drawing. Includes a 16-second demo: mrtnusym.substack.com/p/the-dots-a...

The dots are the renderer: how Math Pattern Gen turns equations into graphics

Thirteen different mathematical structures become one visual system by passing through the same tiny interface: x, y, and radius.

I wrote about why I built Math Pattern Gen. I wanted abstract backgrounds I could adjust—not just generate once. Image generators could get close, but small changes were surprisingly hard. The story behind the tool: mrtnusym.substack.com/p/213365146

I made a small design tool I wanted for myself. Math Pattern Gen turns mathematical structures into adjustable background patterns. Choose a structure, shape it, change the colors, and export as SVG or PNG. Free, no sign-up: martin-ushiyama.github.io/math-pattern...

ChatGPTのCustom instructionsが中々面白い。 GPTの中に3名の異なる人格を定義し、会話は常にあなたの中の複数人による、step-by-step な会話形式で進行し、それぞれの人格を反映してください。って設定したら、ちゃんと設定が反映された人格の3人が会話している。深澤は淡白だし、光太郎はタメ口でフランク、古川は丁寧。光太郎が深澤のことを「深澤先生」って読んでたりして面白い。人格は忘れないけど、話している内容は忘れていくので老人たちの会話またはメメントみたい設定は内容はこれです👇

ゲームにおいて「Twitterによってニュースが民主化されて、ソシャゲの不正などが暴かれやすくなった、ドラクエなども～」と思っていたが、当時のメモやアナリティクスデータを見返したら数値的には違っていた。 2014年頃、ゲーム炎上でRT数が多いものは見当たらず（Twitter検索である程度調べた）、RTが多いのは圧倒的に公式TwitterのRT。事件の炎上記事ではない。自分のサイトのアクセスも検索やはてブがメイン(2016年からTwitterが増え、2017年以降は顕著に増えている）。Twitterが影響力を持ち始めたのは2017年とかそのあたりだったようだ。記憶はあてにならない。
