Give a red blob twelve moods and let the eyebrows do the talking

Procedural Face Generator is a small Red Blob Games experiment in building cartoon expressions from mathematical parameters. Random generation, four color families, and a dozen labeled moods turn a compact graphics study into a quick character-design toy.

What is Procedural Face Generator?

The page treats a cartoon face as a little system rather than a drawing. Five mouth parameters shape the central expression, skew and rotation introduce asymmetry, and separate controls govern eyebrow lift and angle. The visible presets run from Smile and Glee through Grief, Shock, Fear, and two flavors of Anger, while the Random instruction encourages wandering through the larger parameter space. Patel also leaves the workshop door open: the page documents constraints, old Flash roots, and a wish list that includes eye controls, smoother interpolation, shareable URLs, blinking, and continuous animation.

What you can do there

  • Generate simple cartoon faces
  • Choose emotion presets and color families

Why we picked it

The fun comes from seeing emotion broken into adjustable geometry without draining the faces of personality. A dozen plain-language presets make the idea approachable, while the notes underneath reveal why procedural generation is as much about choosing a useful parameter space as producing endless variations.

How to get the most from it

Start with Random several times, then compare nearby presets such as Smile, Glee, and Joy or Worry, Fear, and Shock. Switch color families only after you have noticed what the mouth and eyebrows are doing; that keeps the expression changes easier to read.

Good to know

This is an evolving experiment, not a polished avatar product. The publisher says its articles are free, require no signup, and carry no ads. Face rendering, sliders, animation, mobile behavior, accessibility, privacy, and download or sharing behavior were not tested in this review.
