TubeGraph was a project where we intended to find the best and the worst parts of each YouTube video.

To achieve that, users were able to rate the videos dynamically while watching them, resulting in a graph that shows their most and least liked fragments.

The website run on App Engine from 2009 to 2017, when it was discontinued. A screenshot below features how it looked like; the site is still somewhat browsable (yet not usable) at the Wayback Machine.
