Pavel Trnka’s geometric owl logo on a dark construction grid, with Czech text describing its circle and line construction.
Project screenshotsAbout this Skill
Build a logo mark from a small set of circles and straight lines, using deliberate proportions and vector boolean operations. The workflow documents the grid, circle centers and radii, ratios and optical corrections, then presents the mark on a construction sheet.
Why we picked it
A practical construction workflow that records the actual primitives and optical corrections behind a mark.
What it helps with
- Create a geometric symbol with an explainable construction grid.
- Prepare light, dark and monochrome applications and inspect favicon legibility.
What you can create
The instructions describe a vector mark, a 1200 × 1500 construction sheet with ratio labels and a concept block, PNG previews, light and dark applications, and favicon versions. A six-step process strip and Figma frames are optional.
About the cover
The cover is the author's owl example, shown in a 16:9 composition. The example artwork is licensed under CC BY 4.0 and requires attribution; it is an upstream example, not a new output generated for this listing.
Before you use it
- An AI agent able to follow the Skill instructions and a vector workflow such as Figma, a vector editor, or code that performs path operations and renders SVG to PNG. The Skill supplies design instructions, not a bundled vector renderer.
- The final artwork should be inspected at actual small sizes; output quality depends on the chosen tools and design execution.
