Bomberbot Create

A project to teach kids how to create 2D games. This was created from scratch where I created the initial prototype and then further developed with two other devs and one designer.

(this is the only video I could still find)

Sonar

The sonar was created for Bottlenose. It visualizes relational social media topics in a circular tree. I used d3.force to place nodes, prevent overlaps and animate between states on tree updates.

Timelines

The timelines were created for Bottlenose. Using a simple API, it was possible to configure which data needed to be fetched and how it should be displayed. It was possible to have a stacked bar chart or line chart. The code was based on an Open Source library Rickshaw.
