I just stumbled over The Board via Planet GNOME.
Judging by the video it’s a bit of a mixture between Plasma Desktop (free placement of applets), Plasma Netbook (“pages”), and Apple’s Keynote presentation application (the theme and page flipping animation looks a lot like a presentation I did years ago with Keynote 1.0 or 2.0 when I was still a Mac user).
No idea whether The Board ever enters mainline GNOME 3.x, but it’s great to see that our concept (which is in itself also an evolution of Konfabulator etc.) gains followers from outside our immediate community. This gives us a fresh set of eyes with respect to usability decisions.
Hopefully in the future Plasmoids can be used within The Board and The Board applets in Plasma.
