Featured Challenge:
#188 — Voice Chatbot

In this coding challenge, I build a conversational voice chatbot entirely in the browser with p5.js. I combine three pieces: speech-to-text with OpenAI's Whisper model, text-to-speech with Kokoro TTS, and a "brain" for the bot. I also explore the transformers.js pipeline API and the Web Audio API. For the bot's brain, I start with a simple ELIZA-style therapist, then incorporate a RiveScript number-guessing game, and finally a local LLM.

Visualizing the Barnsley Fern fractal with Processing (Java)!

In this coding challenge, I continue one of my favorite subjects: Algorithmic botany! This video covers the subject of Phyllotaxis, what it is and how it can be used to generate sunflower-like patterns inspired by nature.

Phyllotaxis

More algorithmic botany! Another way to generate a fractal tree is to consider every part of the tree an object, so that we can apply forces and attributes to all the branches and leaves and more!
