As just mentioned [1], the DeforaOS user interface [2] was presented at EuroBSDCon 2012 [3], while running on a tablet device (the WeTab [4]) together with NetBSD [5]. The presentation was recorded, and while waiting for the rushes to be cut and pushed online the slides can be found on khorben's homepage already [6].
