If the point of mak­ing a 10,000-year clock is to get peo­ple to think longer term how do you design that expe­ri­ence so that it real­ly does that? And one of the things that we we real­ized is that peo­ple real­ly need to be able to inter­act with it. That they need to be able to make the moment they vis­it it their own. So while the clock does keep time all by itself with the tem­per­a­ture dif­fer­ence from day to night, it doesn’t actu­al­ly update any of the dials, none of the chimes chime, unless someone’s there to wind it.
