Metric -- Film Description:
"Metric is the whimsical story of the ubiquitous metre. It promises to do nice things for us, like wiping out confusion. It even promises to be simple and logical, a luxury we can hardly afford to neglect. Or is the whole film just a pretext for entertainment? In any case, the film comes up with mathematics that are eminently digestible, even to the arithmetically disinclined."
