Thank you! I spent a lot of time tuning the synth parameters in tonejs to try to get something I was happy with.

The scales are based on the Japanese "in" pentatonic scale (sometimes called the Sakura scale), which I find really pretty.

I'm experimenting with a musical instrument design, using hand rotation to change tempo and note cycles.

Created with javascript, mediapipe computer vision, tonejs, threejs.

This runs in real-time in the browser.

thank you. I thought of this on a roadtrip and was very keen to start building it when I got home.

Show HN: Snacker News; a hands-free HN. The more you eat, the more you learn

getToTheChopin — Thu, 24 Jul 2025 17:46:34 +0000

I made a hands-free HN reader using speech and face recognition

Speak to navigate the feed; eat doritos to scroll an article

Live demo (please use Desktop Chrome): https://funwithcomputervision.com/snacker-news/

This works in real-time in the browser using a regular laptop webcam

All speech / face recognition is done locally (none of your data is stored)

Tech stack: HN API, mediapipe face landmarks, web speech API

Thanks for checking out my silly web app and I would appreciate any feedback!

Show HN: Planking for penguins, a real-time exercise tracking game

getToTheChopin — Sat, 12 Jul 2025 20:40:59 +0000

This uses mediapipe AI vision to detect when the player has proper plank form (knees-hips-shoulders in a horizontal line, elbows low)

Also using threejs for visuals and tonejs for audio

It runs in real-time in the browser, using a regular laptop + webcam

Live demo: https://www.funwithcomputervision.com/chinup/

You can track chin-ups, push-ups, or planks. I will continue to add more exercises into the game

Any feedback would be appreciated!

I'm creating a fitness game on the web, where you do exercises to save pets

Here's a live demo (camera access required): https://www.funwithcomputervision.com/chinup/

I've added push-up mode as well, and you can choose whether you want to rescue cats or dogs :)

Tech stack: mediapipe computer vision (body pose tracking model), threejs, tonejs

I'm actively working on this, so please let me know your feedback / other exercises you want added!

Show HN: Do a chin-up, save a cat (mediapipe and threejs real-time browser game)

getToTheChopin — Wed, 09 Jul 2025 11:08:46 +0000

I made a game that forces me to work out

Do a chin-up, save a cat!

Created with mediapipe AI vision (for body tracking) and threejs (for visuals and animations)

It runs in real-time in the browser

As next steps I want to:

* improve layout on mobile

* add a global scoreboard

* allow people to upload their own cat pictures to use in the game for extra motivation :)

please let me know of any feedback or ideas!

getToTheChopin — Mon, 23 Jun 2025 14:12:46 +0000

I made a body movement game. You jump around your living room to dodge lava.

Created with threejs and mediapipe computer vision.

You can play the game here, it runs on the web without any installs or downloads: https://www.funwithcomputervision.com/demo7/

getToTheChopin — Thu, 19 Jun 2025 00:51:49 +0000

This is a computer vision experiment, using voice + hand gestures to control a shader animation.

This uses a liquid Chladni pattern, with controls for color and wave frequency / amplitude.

Created using threejs, mediapipe computer vision, and web speech API.

Show HN: Hand-controlled arpeggiator, drum machine, and audio reactive visuals

getToTheChopin — Fri, 13 Jun 2025 15:56:30 +0000

This is a demo video showing a hand-controlled arpeggiator, drum machine, and audio reactive visualizer

Runs in real-time on the web, using a laptop webcam

Created with threejs, rosebud AI, mediapipe computer vision, and tone.js

Work in progress live demo: https://rosebud.ai/p/f8f8cd80-1f68-466a-9da2-09cc0c354f45

Next I want to add new synth sounds and find an easy gesture to change the drum patterns

Any feedback would be appreciated!

I'll try it, thank you! I separated them into completely different interaction modes to avoid misfires, but there's definitely room for efficiencies

It's a shame that computer vision tech like Leap / Eyetoy / Kinect didn't have lasting power. So much fun to build with

I'm working on a couple other body movement concepts and hope to share soon :)
