hi DN community, I am the creator of Font Playground https://play.typedetail.com/, which is a playful side project to experiment with variable fonts. I have just updated the web app with a bunch of new features, you can create interesting compositions with variable fonts and save it to CodePen. You can reopen saved comp later as well. Try out the font Spooky, it is ... spooky :) It is part of 13 newly added fonts designed by the Black Foundry.
