Colors In Rhythm Series by 101 Apparel

Yesterday I was browsing around 101 Apparel's website (as my previous post on their "Musica de Sud-America" t-shirt might indicate) and I came across a limited edition series of prints and t-shirts under the label "Colors In Rhythm."  These t-shirts have very cool geometric patterns without any text.  What I like about these patterns is that they don't feel mathematical to me, like they were formed via some algorithm.  Perhaps "geometric" isn't a good way to describe them, although that is how they are described on the website.  The patterns are supposedly inspired by mid-century design, but they remind me more of tribal patterns you might find in Sub-Saharan Africa or in Oceania.  There are seven t-shirts in the collection, and each come in several colorways (see the whole collection here).  They are also made of 100% organic cotton.  I'm not sure if 101 Apparel plans to continue Colors In Rhythm (the last collection was from last year), but I hope they do because these t-shirts are fantastic.
