This is a browser extension for Chrome/Brave and Firefox 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.
Install from the Chrome Web Store
Install from Mozilla Add-ons site
By default, the extension only loads on github.com. You can manually enable the extension for your Enterprise domain by clicking the extension icon and choosing Enable Isometric Contributions on this domain.
