It looks exactly like this: http://www.elonlinesalg.dk/lk-fuga-afbrydere-hvid/lk-fuga-lysdaemper-touch-350uni-hvid.htm (the lower part/frame of the "dimmer box" in the video, is the only original part) - It has then been built in a standard Danish LK outlet-box.
However, it's a LK type (Lauritz Knudsen) who makes the Danish standard formats for wall plugs. You can also just remove your regular on/off wall switch for your diner table lamp, and replace it with this one, and bingo; you can dim the light with beo-remote control.
It propably won't fit very beautiful in non-Danish homes, due to it's "Danish standard size".
In the video it seems attached to a wall plug.
I would recommend this one for you: http://www.rabat-vvs.dk/detail.asp?x=&menu=..2,57&detail=4859 It works beautifully, however I wouldn't know if it fits US 110 volt, I use it in Denmark (230 volt)
