...the Royal Melbourne Institute for Technology (Australia's MIT or Caltech, for those not in the know) has released Sans Forgetica
, a font "scientifically designed to help you remember your study notes".
At first, it looks like your typical leftalic display font, but they go into a lot of interesting points. I personally intend to download this just to play with it, and I suspect that its ultimate use won't be for study notes, but as a display font.
Considering memory improvement, there are tons of resources online, from world memory champion Dominic O'Brien to all kinds of YouTube educational channels. You know, the ones making the scam obsolete.
