Re:Show HN: Lampjack - live 3D visuals in a that follow your... by jamiemcdonnell on Monday November 09, 2026 @10:42AM (#50427111)
I built this app as I'm a percussionist and I wanted reactive visuals while I play with a guitarist and singer or a band, which fit the mood of the music we are playing.

The app listens for sound from th mic, a midi device or music playing in a separate tab.

You can patch any aspect of the music to aspects of the visuals such as bass > temp, pitch > hue etc.

There are a multitude of scenes already created, and it is easy to create your own custom scenes built on the presets I provide - I will be adding more in time.

The app needs a browser which supports the WebGPU APIs - I mainly run it in Chrome.

You can try it for free, or for unlimited use there is a low monthly subscription.

I would really appreciate user feedback, thoughts and ideas, or if you are interested in partnering to help this product and it's userbase grow, please do get in touch - I am waiting for your feedback and input.
