This is an extension for Chrome, Safari (see note below), and Firefox (beta) that lets you toggle between your regular GitHub contribution chart and an isometric pixel art version. It uses obelisk.js for the isometric graphics.
Besides being sort of neat looking, this view is interesting in that it highlights the differences between the number of contributions with more granularity. This isn't meant to completely replace the standard 2D graph though, because in most ways it is actually less useful. For example, there are no axis labels, shorter bars can be hidden behind taller ones, you can't hover over a bar to see the day and count, etc.
Installation
NOTE: When installing this extension, you will likely see a warning about it needing access to all domains, not just github.com. This is required for people who are using GitHub Enterprise since it can be installed on any domain name.
Chrome
The easiest way to install the extension is through the Chrome Web Store:
Firefox
The Firefox extension has not been verified by Mozilla, so only Firefox Developer Edition is supported at the moment. Set xpinstall.signatures.required to false in about:config. Download the isometric-contributions.zip file and open it in Firefox Developer Edition. Or, in Add-ons Manager, choose "Install Add-on From File" under the wrench icon and choose the zip file you downloaded.
Safari
Download the isometric-contributions.safariextz and then double-click the file to install it.
I'm no longer able to build Safari extensions because you now need a paid Apple Developer account to do so. I've decided not to spend the $99 for an account since this is the only thing I'd use it for.
Developer mode
If you want to hack on the extension, you'll need to install it manually. First clone or fork this repo. Then, on your Chrome Extensions page, make sure "Developer mode" is checked. You can then click the "Load unpacked extension..." button and browse to the chrome directory of this repo.
Hacking
To hack on the extension, you'll first need to make sure you've installed it in Developer mode (see above). Once you've made changes to the extension, go back to the Extensions page and click the Reload link under the extension entry.
As of v0.8.3, this project uses CoffeeScript. To compile the iso.coffee file to all extensions:
