Dalton Maag are now distributing all their fonts for free under a trial licence. Simply go to their website https://www.daltonmaag.com/ , sign up for an account (you can use a throwaway email if you want) and download the trials.
Trial fonts have the entire glyph range and all OT features, they aren't crippled in any way and are the latest versions, the only difference is that the font name identifies it as a trial. The licence allows their use on up to 5 machines for academic, speculative or pitching purposes. Obviously, if you use the font in a final project you need to pay for it.
It's gratifying to see D-M engage in such a generous and forward-thinking attitude, and they deserve our support.
