Spacetime Maps
A map where distances mean time and not space. Points that are close but take a long time to travel between get pushed away from each other, and vice versa.
The map is available here and the code lives here.
Update: Later I also posted on the webapp on Hacker News to promote the video and the post made it to the front page. I guess I should have done that sooner because it gave me useful feedback about what people like and what they find confusing. But it only sent very few people to the YouTube video: about 13k people opened the webapp but only 55 of those (0.4%) clicked the video link from there. So from the marketing perspective, it wasn’t a success. Lesson re-learned: post sooner, learn stuff.
