@djsundog I was like "wait this looks familiar" and then searched the page for "OLPC" and.. yup there it is. I was geographically adjacent to a lot of the primary development on that project because I lived near MIT at the height of it, so I spent a lot of time with people who worked on it and at workshops and talks.
@darius yeah! it's at the top of my list of "interfaces that should have stuck", and their design docs (along with Raskin's "Humane Interface") are still a gold mine of good ideas I'd like to see picked back up.
