Ask HN: What cool stuff have been built with JavaScript?

Looking to learn Javascript and build some cool stuff for my startup http://www.traction.vc

Before learning it though, I'd like to get inspired about what's possible. Thus collecting a list of cool stuff built with Javascript. What cool apps/websites/experiments that you know of have been built with Javascript? List them here.

I wanted to learn JavaScript, so I made a few small programs.

Fallout Hacker Helper http://faehnri.ch/fhh/ - a utility to help with the hacking mini game in Fallout 3

WRAP http://faehnri.ch/wrap/ - Web Register Assembly Programming, a browser version of Daniel Dennett's RAP machine, a simple register machine and language he uses for some theory of mind concepts (read his Intuition Pumps)

Disrupt Inspiration http://faehnri.ch/disrupt-inspiration/ - something I made quick after a friend and I were joking about startups. Generate startup ideas in the form of "X, but for Y." Submit ideas!

Vector map rendering (https://www.mapbox.com/blog/mapbox-gl-js/) editors (https://atom.io/) data visualization (https://github.com/mbostock/d3/wiki/Gallery) compressing data (https://www.npmjs.com/package/gzip-js) image manipulation (https://www.npmjs.com/search?q=jpeg)

My point is: almost anything can be build with Javascript.

SilkJS is neat and much of it is written in JavaScript (the rest is C++) -- http://silkjs.net/ "SilkJS is a command shell built on top of Google's v8 JavaScript engine, highly optimized for server-side applications"

StatsD[0] is pretty awesome and probably the only server side JS tool I would ever use.
