Gah! You are correct about the map not resizing. Has to do with the library I used, called Datamaps. I could listen for window resize events, but for the MVP I figured it wasn't worth it. Thanks for pointing it out though, I'll get to this.
What did you to do get that map stuck in your screenshot? Never seen that before.
I don't think I did anything - I hardly interacted with the page at all, except from skipping a Soundcloud track once and possibly resizing the page.
At one point, it switched from "world view" to "US continental view" to show a hyperlapse from Miami, and then got stuck there in perpetuity.
Edit — or maybe I had a blackout and this is resize-related as well. It would make sense if I shrank the window, so half of the map got stuck outside the window. Never mind then :)
Edit: also, the map seems to get stuck: http://i.imgur.com/YOVzJwz.jpg
