There's no version in a black box, but you can find small black plastic enclosures that you can use. You would have to make the holes themselves. Due to the straight connectors coming straight up off the board and the depth the box will have to be, it will be kind of awkward plugging in the sensors and relays (deep hole).
Eventually I will look for some 90 degree pin headers that will work (I totally forgot I wanted to do this), so the sensors can plug in from the side, to a depth that is not too deep, like plugging in the other connectors would be, and get some of those enclosures (fry's or custom) to put mine in. This would require desoldering/soldering though, which by your first post I'm assuming you're not into, can't, or don't know how to yet. You could always do it from the top, but I think it will be prettier if I can plug in from the side, like a car alarm.
It would be nice, say if you don't want to use a AV autoswitching feature, and see the video say, framed within a skin. But at this moment, the ability of the brain's software to talk to other software is limited. But if your video software is running in the background and will do what you want it to do by first, getting focus, and second, recieving a keystroke, then there might be a way. Further development by Fusion's 'mad scientist' coder gets us closer to doing things like what you want every day.
I think I can see what you want, in my mind. And it would be pretty cool. Would be neat for home automation use as well.
EDIT:
I have finally achieved the FLACid state...neat.
