Font Playground is built for three groups of audiences.
The first group of audience is typographers and designers, who would like to play with fonts that are built with the latest font technologies, such as variable font. It is a playground to fully explore what these new font technologies can offer and how they can be beneficial to your creative workflow.
The second group of audience is me, as a Type Tool’s UI/UX designer. This is a playground for me to test UI experiments for variable fonts and other new upcoming font technologies. One of the key points to the success of new font technology is adoption by design tools, and furthermore, designers. How can design tool present variable fonts in a way that is useful but not too complicated to handle? I hope to find the answers with this playground.
The third group of audience is the type designers and foundries. This is a place to showcase the work-in-progress, cutting-edge font creations. It is a playground to see how fonts are being presented and used in future design tools. How fonts are used can also inform how fonts are made, and what standard should be defined.
This is a great introduction to variable fonts and it’s a great playground to quickly see everything that you can vary in action. Adding multiple text lines looks like it will be landing soon.
Note: I believe this doesn’t work yet in Firefox because they don’t fully support Variable Fonts.
