The Nelson clocks were first born from a festive evening of collaboration.... Nelson recalls: 'And there was one night when the ball clock got developed... a couple of fellow designers came by... we started making doodles. Then someone said, 'This is a good way to do a clock,' and he made some utterly absurd thing. Everybody was taking a crack at it, pushing each other aside and making scribbles.... and the next morning there was this roll of drafting paper and somewhere in this roll there was the ball clock." These clocks are produced from the original design documents from the Nelson archive.
