I know it may be 'designed' for iOS and mobile screen formats, but it seems to me a seriously bad decision not to have a 'show it to me anyway' button, along with a disclaimer that it (might) be broken on $platform...
And saying 'fork it' for an issue this trivial is not a great way to promote yourselves.
I think the main blocker with opening it up for desktop is having to design a more appropriate layout. Not impossible, just time-consuming. And as Ben says, it is intended as a tech demo.
I'm sure we could add a button to show it on devices that wouldn't experience what it was 'designed' for… but really, we open sourced it to share some of the things we learnt along the way—not pour time into testing over various fragmented devices.
I think the idea of the app is awesome, and it's good that we can read the source. It's just a bummer that I can't use it in its current state.
If this is what people would have to do, why would anyone do that over native?
