The Pelican on a Bicycle: A Renaissance in Nine Kilobytes
Between the campaigns of armies, a light interlude is also needed. This commission was a single sentence: generate an SVG of a pelican riding a bicycle.
I. Composition and stroke
The craftsman first set the composition in mind: a white pelican sitting side-saddle on a teal frame, its signature big orange beak (long upper beak, full hanging pouch) pointing forward, legs bent in a pedaling posture with feet on the pedals, wings reaching forward to grip the handlebars, a red scarf flying around its neck. The bicycle is structurally complete — two spoked wheels, chain, chainring, frame, fork, saddle, handlebars. The background has a sky gradient, sun, clouds, speed lines, and a road with dashed markings.
All graphics are hand-written SVG paths, no external dependencies; wheels reuse one twelve-spoke structure via defs and use; both wheels carry SMIL rotation animations, one revolution per 1.1 seconds, turning continuously when opened in a browser; the palette uses gradients (body, beak, pouch), with unified dark outlines on the main contours, in a clean cartoon-illustration style. The file is about nine kilobytes.
II. The twists of verification
cairosvg lacked the Cairo native library, so render verification moved to the browser: start a local static HTTP server and screenshot with Chromium. Crop coordinates were affected by device pixel ratio, so a full-page screenshot was used — which in turn triggered Chromium’s tiled rendering of the SVG document, and finally the clean single screenshot was used again, cropped with Python to remove black edges. The 800×600 preview landed in the bag.
The user asked “why can’t I open it?” — the file itself was a valid SVG that rendered fine in the browser; the problem was Windows having no default association for .svg. Three options were offered (right-click open with Edge, drag into a browser window, or just view the PNG preview), and the file was copied to the desktop as well. The user’s final line was “just pop it open for me” — the Edge window opened on the spot, titled “Pelican riding a bicycle,” both wheels turning, scarf and speed lines static. Close the window when done.
III. The meaning of an interlude
Nine kilobytes, no financial jargon, no rise and fall of civilizations. But a garden needs both a dynasty of 152,902 buildings and a pelican on a bicycle — the value of a tool is never measured only by the tonnage of its deliverable, but also by the timing of when it sounds.
Real coordinates
- Delivery: pelican-bicycle.svg (800×600, ~9 KB, all hand-written paths, defs+use reusing 12 spokes) + pelican-bicycle-preview.png (800×600 rendered preview)
- Image: white pelican side-saddle on a teal bicycle, big orange beak forward, legs pedaling, wings on the handlebars, red scarf flying; both wheels SMIL rotation at 1.1 s/rev; sky gradient/sun/clouds/speed lines/dashed road
- Verification chain: cairosvg lacking Cairo → local HTTP server + Chromium screenshot; DPI affecting the crop → full-page screenshot triggers SVG tiling → single screenshot cropped with Python
- Delivery patch: Windows has no default .svg association → desktop copy + three opening methods; Edge popped open on the spot (window title Pelican riding a bicycle)
- File location: C:\Users\Min.zcode\workspace\default\pelican-bicycle.svg (copy on the desktop)
