Hi there! 👋 


Leon van Kammen likes to use technology like 3D, WebXR, music, FOSS software in a harmonical way using symmetric technologies like P2P networking characterized by net neutrality, offline-first, multi-protocol decentralized web and an Open Internet and philosophies which decrease activism through abductional reasoning as promoted by pragmatism transcending humanity via abductive reasoning , and increase by applying symmetric feedback loops inspired by integral theory which shows that nobody can be 100% wrong. This, as well as emergentism , a non-linear look at reality, as explained by Karl Popper, who demonstrated the limitations of predicting the future black swan, based on the past and disciplines like cybernetics which are bipartisan by introducing symmetric interoperability between both private sector and digital commons, sustainability for both private/public tech,


XR Fragments

A specification for 4D URLs. Spatial navigation and referencing for XR designers, experiences and browsers.

SearX(R) - Immersive search

An immersive meta-search engine, a privacy-friendly opensource one.

XRSH - virtual machines in WebXR

Worlds first WebXR virtual machine: run a tiny linux in your WebXR session, and save/restore sessions offline and online via remotestorage protocol.

MIDI soundfont sidecar spec

A simple, implicit spec for media players, DAWs and midisequencers, to automatically load soundfont files when playing MIDI files, enhancing the playback experience without requiring user configuration.

voice/paper hashtagbibs

I've created the bibs spec: an extension of hashtags, which empowers citizen annotation and introspection.

symmetric proof of stake

The future is bright ❤️ for both private/public tech: Symmetric interoperability between digital commons and private sector is already converging.

Be ready for the future

promoting offline-first 3D hypermedia first, de-emphasizing centralized online (compute) technology.

CocaCola FuzeTea

A travelling realtime installation across major big festivals in Europe: I did the sounddesign for YFXlab.

Learn thru all devices

Forget mp3 or Spotify, Leon publishes his tracks as a single-file WebXR experience

ASCIISTEP16 specification

I've created the spec so pckeyboards can act as musical stepsequencers, currently implemented in milkytracker

ASCIISynth specification

I've created the spec so people can share synthesizer-presets via text.

textual kanbans

Exploration of directory-based kanban-boards which emphasize the power of batch and interactive text (commandline)

Symmetric Opensource license clause

The symmetric opensource-clause promotes syntropic FOSS , basically faircopy (between copyleft and copyright) which promotes symmetric, reprocity-based software-development for humans, not serverparks by extending software licenses, to foster symmetric, post-growth commercialisation.

Telescopic text

Links allow teleportation, telescopic text allows introspection.

Worldwide & and remote

Working with clients & global commons orgs across the world since 2004!
