I thought about this a few years ago, finally made it a few months ago(as of 04/2010). So it just occurred to me, why not upload it here? It's not a true Metric Clock, this just splits the day into 20h-100m-100s. It doesn't modify day, week, month or year length. You only need to watch it for a few seconds to figure out what comes next. Have fun for 1h12m(or should I say 1 hour, huk-yuk)!
