Ray-traced black holes and atmospheric simulations you can manipulate with your fingers.

Strengths

•Ray-tracing and atmospheric physics simulations run smoothly in WebGL with touch controls
•Twenty polished visualizations curated from classic HN demos into cohesive collection
•Multi-touch interactions designed specifically for tablets and touchscreens

Weaknesses

•Primarily exploratory rather than solving a specific practical problem
•Niche audience of visualization enthusiasts and educators

Post Description

I started out building and tweaking visualizations of some of my favourite HN posts over the years. Then I started mashing then up, adding more ideas and taking inspiration from math papers. Here it is now, with 20 visualizations released and over 100 sandboxed.

All WebGL + TypeScript, prioritizing touch and multi-touch for the interactions.
