This is the latest iteration on the Attract project. We are building a unified framework called Pillar. Pillar will combine Blender Cloud and Attract. You can see Pillar in action on the Blender Cloud.
The icons on the website are drawn using a custom font, stored in [pillar/web/static/font](pillar/web/static/font). This font is generated via Fontello by uploading [pillar/web/static/font/config.json](pillar/web/static/font/config.json).
Note that we only use the WOFF and WOFF2 formats, and discard the others supplied by Fontello.
After replacing the font files & config.json, edit the Fontello-supplied font.css to remove all font formats except woff and woff2. Then upload it to css2sass to convert it to SASS, and place it in [src/styles/_font-pillar.sass](src/styles/_font-pillar.sass).
Don't forget to Gulp!
