Lonely LaTeX Account Sublimates Heartbreak Into Suggestive TikZ Surface Plots

Level 1: The Love Letter Written in Graph Paper

A man is too shy to call someone he's missed for thirty years, so instead he draws her — but because he's a math person, he doesn't sketch with a pencil. He writes equations that, when the computer draws them, come out as a blushing pink shape that looks suspiciously like the person on his mind. It's funny the way watching someone bake an elaborate seven-layer cake instead of saying "I like you" is funny: all that skill, all that effort, pointed at everything except the one simple thing he's actually trying to say.

Level 2: TikZ, MUDs, and Engineered Curves

The vocabulary behind the laugh:

• LaTeX: the document preparation system academics use for papers and theses — famous for beautiful math typesetting and merciless error messages.
• TikZ / pgfplots: LaTeX packages for drawing programmatic graphics and plots. You describe a figure in code; the compiler renders it. \addplot3[surf] draws a 3D surface; shader=faceted interp controls how each little mesh facet is colored — here producing the smooth pink gradient.
• Parametric surface: instead of plotting z = f(x, y), you define x, y, z each as formulas of two parameters. Sweeping an angle through cos(2*pi*x) and sin(2*pi*x) spins a profile curve into a rounded 3D shape — like a lathe for math. The exp(-(y-a)^2/b) terms are Gaussian bumps: smooth hills you can place anywhere on the profile, which is exactly how you'd sculpt, say, anatomy.
• MUD (multi-user dungeon): a 1980s–90s text-based online multiplayer game — the social internet before graphics, where "walking with her online" meant typing go north together.

The relatable kernel for any developer: displacement activity. Can't face the scary thing (the text message, the production incident, the thesis chapter), so you do an absurdly elaborate technical thing instead and call it productivity.

Level 3: Sublimation, Faceted and Interpolated

There is a lot happening in this screenshot, and every layer rewards inspection. The verified LaTeX.org account (@TeXgallery) — a project account that exists to share typesetting examples — posts what reads like a diary entry left out in the rain:

"It's Friday late at night. I walked with her online 30 years ago in a multi-user dungeon role-play game. Met her in a café in Hamburg 20 years ago. I had too much wine tonight. Should I call her? Text her? I'm plotting functions in TikZ to distract myself."

The timeline alone is a complete portrait of a certain generation of European hacker: romance kindled in a MUD (a text-only multiplayer world from the telnet era — courtship at 2400 baud), one café meeting in Hamburg two decades later, and now wine and pgfplots. But the actual joke detonates below the fold: the "distraction" code, shown in a browser at a LaTeX guide page with its orange TYPESET / COMPILE button, is an \addplot3[surf, shader=faceted interp] whose parametric radius function — Gaussian bumps like 0.1*exp(-1*(y-0.8)^2/0.6) modulating cos(2*pi*x) and sin(2*pi*x) sweeps — renders two pink-gradient 3D mesh surfaces shaped, with zero plausible deniability, like a feminine lower body. Hence the screenshotter's caption: "LaTeX account is thirsty af."

This is sublimation in the strict Freudian sense, executed in the strictest typesetting system known to humanity. The craft detail is what sells it: those aren't traced curves, they're designed equations — someone tuned Gaussian means and variances (y-0.8, y-0.1) until the hips were right, which is somehow both more chaste and infinitely more dedicated than just texting her. The surface-of-revolution trick (radius ra(y,x) swept through cos(2πx), sin(2πx)) is a legitimate pgfplots technique you'd find in any gallery; weaponizing it for longing is the innovation. And the deepest irony for anyone who's fought TeX: his loneliness compiled on the first pass. Most of us can't get a table to stay on the right page.
