One of my old coworkers left to do his own thing, centered around play and learning music.
Here's a talk he gave about it:http://www.extraordinaryfacility.com/2017/04/the-tune-zoo-other-stories/
Oh wow I love this talk! Looks like he’s got a cool dev tumblr blog thing too!
Please feel free to invite Matt here! It looks like he might be interested in Chaim’s paper on Play Design too.
