I animated my email pfp with AI
My cold emails got 4x more open rate than with the static one
4x open rate from an animated pfp is wild. Small detail, but it's the first thing people see in the inbox.
Such a lovely concept!
Very cool
Clean design and smooth animation! What AI did you use to create the movement? Claude?
To work Alex !
Smooth!
Where's the animation? 🙈
4x open rate just from the pfp is wild. Did it work the same across Gmail and Outlook? Curious how it shows up for different clients
Interesting experiment, Alex. Did the higher open rate translate into more replies too? I’d love to hear how you compared the versions and which email clients displayed the animation. Useful context for anyone considering a similar test.

Clear results build trust. Patients know what their exam means and what to do next, and doctors spend less time explaining the same numbers.
I never see design like this before thats unique 🎉🎉🔥🔥

I built this project to test A civic bureau seals your letter to 2126 under molten wax, witnessed. A civic bureau that seals letters for exactly one hundred years. Write a message to 2126, watch it set in wax, and receive your engraved certificate of deposit. The core engineering challenge was sustaining uncompromised 60 FPS rendering using Canvas2D while handling continuous user interaction without framework overhead.
WHAT I WAS TESTING:
I focused on two core engineering benchmarks:
Precision implementation of wax-seal SVG under continuous interactive user input
Sustained 60 FPS render performance and zero-dependency browser execution
THE TECHNICAL SIDE:
Engineered directly in the browser with Canvas2D, Wax-seal SVG. The application runs without third-party frameworks or build-step dependencies, using hardware-accelerated rendering and custom event loops to achieve zero-latency response.
Everything executes in the browser using Canvas2D, Wax-seal SVG. No third-party frameworks, no heavy runtime bundles, and zero external tracking.
WHAT I LEARNED:
Balancing the mathematical rigors of wax-seal SVG with tactile browser interaction required tuning event throttling and memory allocation to eliminate all garbage collection stutters.
Finding the sweet spot between mathematical precision and frame budget took careful profiling, but the result runs at a steady 60 FPS even on modest hardware.
TRY IT YOURSELF:
The live build is deployed on Netlify. Open it in your browser, test the controls, and observe the render response times.

WHAT I WAS TESTING:
I focused on two core engineering benchmarks:
Real-time topographic contour line extraction using Marching Squares
Mountain ridge carving and hydrographic river basin generation
THE TECHNICAL SIDE:
Combines domain-warped fractional brownian motion (fBm) with Marching Squares contour generation. Renders vintage parchment styled topographic maps with seeded coordinates.
Everything executes in the browser using Canvas2D, Procedural Cartography, Contour Line Marching Squares. No third-party frameworks, no heavy runtime bundles, and zero external tracking.
WHAT I LEARNED:
Contour line marching squares often generated disconnected micro-segments. Stitching adjacent line segments into continuous polyline paths allowed smooth canvas stroke rendering.

Really nice map detail
