Can I build an interactive 3D Rubik's cube in Processing? Yes! Someday I hope to return to this project and add an AI solver!

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.

rotation matrix
In this coding challenge, I visualize a 4D Hypercube (aka "Tesseract") in Processing (Java).
Can I draw and rotate a 3D cube using Processing's 2D renderer with just some math?!?! Yes! Watch to learn more about rotation and projection matrices along with perspective and orthographic projection!
