Sans Forgetica Typeface
It's not often you see a typeface deliberately designed to be hard to read. Yet the difficult design of Sans Forgetica has a purpose. A fun mashup of "Helvetica" and "forget," its design is slanted seven degrees to the left and has breaks in each letter's structure, making your brain work harder to identify each word, and thus boosting retention. Created by Melbourne's RMIT University Behavioural Business Lab, it's available as a free download or as a Chrome Extension.
