Implemented a multi-layer perceptron using the Perceptron Training Rule and Gradient Descent Delta Rule, without ML libraries — covering
forward propagation, error calculation, and convergence tracking across training epochs.

Hello everyone!
You might recognize me from the unique faceless avatar pfp, so with this submission, I wanted to find ways to make the faceless avatars series more accessible for everyone.
Wonder chat has helped me execute the foundations for a faceless avatar studio where I can reuse various poses, hairstyles, accessories like hats and glasses, thanks to the vector models of arrow 1.1 max and the friendly interface of Wonder.
After generating various vectors, the illustrations were close to the style so the refinement and improvements were minimal.
I then focused on building the UI prototype, with the help of Wonder chat, where it further helped me discover new concepts on how to visualize this.
Final demo of v0.1 was then built with an MCP connection of Claude code and soon to be live for everyone to use!
Check out the design process from Wonder here: https://app.wonder.so/thoroughly-peaceful-imp/files/019f38df-c790-7860-a31a-571472e3b60c
The faceless avatar studio sounds intriguing; how do you plan to expand the range of accessories in future updates?
The renaissance painting next to the terminal window is an unexpected pairing that actually works, gives it more personality than the usual gradient blob hero. What made you go with that contrast?
Air Sculpt - sculpt with your bare hands, in the air.
For 30,000 years we've shaped stone with our hands. I wanted to know: what if you still could - without ever touching a mouse?
Air Sculpt is a browser tool where you sculpt a real 3D marble form using only hand gestures, tracked live through your webcam, then export a genuine, 3D-printable file. The oldest art, in the palm of your hand.
🏛️ What it does
Pinch in the air to carve - the marble swells where you point, like clay
Press to push in, Smooth to polish, two hands to scale, a fist to rotate
Switch materials - marble, clay, bronze, alabaster
Finish → name your piece → export a real .STL you can 3D print
Every sculpture lives on in a museum gallery you turn through like a real exhibition
The whole thing is built as a classical sculpture museum - warm marble, golden skylight, an atelier you step into. Modern hands, ancient craft.
✨ How Wonder made it possible
I designed the entire world in Wonder:
Wonder Chat — built every screen (atelier, gallery, reveal, about) by describing them and reshaping on the canvas
Shaders — the golden museum light, drifting marble dust, and glowing material spheres are all real Wonder shaders, the whole atmosphere, not decoration
Figma paste-in — sketched a frame in Figma, dropped it in, Wonder matched it
MCP → Claude Code — because in Wonder the design is real code, I connected straight to Claude Code and shipped the whole thing live. No handoff, no rebuild. What I designed is what shipped.
The hand-tracking runs on MediaPipe + Three.js; Wonder was the design engine behind all of it.
I walked into Wonder to design a museum and walked out with a working product.
Built for the Wonder Challenge
This sounds incredible! How intuitive is the hand-tracking for intricate details?
