Now you can make Greta the Mindless Climate Puppet say anything you want! A graphic designer has created a new, free typeface called “Greta Grotesk” based upon the lettering of young Miss Thunberg’s signs. You can download the font from this page. The font is in OpenType format (.otf), which is compatible with many systems; here is how to install such fonts on Ubuntu Linux.
If you’d like to make your own sign, here is a blank template with which to start. To preserve resolution, the template is a large (2040×1360) image. After you’ve added your text, scale to something appropriate for your application (for example, 640 pixels wide for the Web) and export the smaller image.
