[J2K]

Fun test. Also if anyone's interested in Helvetica or typesetting in general just watched a pretty good documentary recently that got me more interested in the topic: http://www.helveticafilm.com/, also available on netflix: https://movies.netflix.com/WiMovie/Helvetica/70076125

Sorta similar to the 'Objectified' doc that was recommended by HackDesign but I actually liked this one better.
