Lively4

I co-created and maintain Lively4, a live, self-sustaining, and wiki-like web-based programming environment and application platform. Lively4 integrates the spirit of Squeak/​Smalltalk with modern Web technologies.

Demo Code Paper
Active Expressions

I developed Active Expressions, a reactive primitive that adds reactivity as a first-class citizen to state-of-the-art languages such as JavaScript, Python, or Smalltalk.

Demo Code Paper
d3 Bundleview

An interactive visualization to explore massive hierarchical data structures with relations like software projects with dependencies. Edge bundling provides high-level insights while the interactions allow you to focus on specific parts of your dataset.

Demo Code
floom

I created floom, a fluid simulation written in JavaScript. floom uses the Material Point Method, a hybrid variant of particle and grid systems. You can switch between computational models and change material parameters on the fly.
