I am still working on Eigen, a self-hosted alternative to Google Workspace.

Six months ago I wrote about Eigen: a European Google Workspace alternative where you own your data.

This is a guest post on my website.

Last spring I started wondering: how hard would it be to build my own Google Workspace?

I’ve recently created a simple WebGL demo that showcases a lightmapped scene with multiple instances of the same mesh.

In my latest project, I’ve explored WebGPU to create a ray tracer capable of rendering the Stanford dragon model (87,130 triangles) in real-time.

Together with my colleague Johan Holwerda, I’ve created the RenderQueue, a platform where we’ll share a selection of WebGL and WebGPU demos we’ve developed over the past decade.

Five years ago, I launched Turtletoy, an online platform that enables users to create plottable generative art using a simple Turtle graphics API.

Over the past few weeks, I’ve developed a custom e-ink family calendar as my first Raspberry Pi project.

I am excited to share my latest (award-winning!!

I recently collaborated with Mark Knol on “Contemporary Relief” – a generative art project that creates geometric patterns using a WebGL path tracer.

Over the past few months, I have spent some free time developing Dittytoy: an online platform that allows you to create music using a minimalistic javascript API.

I love the rendering style of Townscaper by Oskar Stålberg.

After creating Turtletoy, it was easy to create a second toy website: Oneshader.

I’ve been playing with Truchet tiles in my latest Turtletoy project.

This shader is a proof of concept to find out if I could create a “typical” Shadertoy shader, i.e. a shader that renders a non-trivial animated 3D scene, by using a ray tracer instead of the commonly used raymarching techniques.

I created a reference shader with ray-primitive intersection routines on Shadertoy.

Since the introduction of the Nvidia RTX graphics cards last summer, ray tracing is back again.

This is the first year that I have participated in the Global GameJam 2019.

I have ported most of “ln, The 3D Line Art Engine” by @FogleBird to javascript so it can be used on Turtletoy.

Yet another Cornell Box: a path tracer in a single fragment shader on Shadertoy.
