This is great - I saw this marble driven, wooden, binary adding machine on my friend Doug Clinton's 'blog and I just had to add it here.
As Doug says "This is just awe-inspiring (for any self-respecting geek, that is)" - and I really couldn't agree more.
I showed the clip to a few of the guys in our City (London, that is) office today - and they unanimously agreed too.
Doug's post permalink "A binary adder made of wood. Incredible video" and YouTube's post link "Marble adding machine" - just to keep it all together.
