Jean Prouve wall lamp for inspiration

I was looking up Jean Prouve, and came across this excellent wall lamp. It thought I would post it as inspiration while you all work on your boards.  It it a really simple, elegant and functional piece, but also somewhat outlandish, in a good way.  It looks like you swing the big arm back by moving the spherical knob. There's a really elegant cable stay to support the long canteliever. enjoy.
