Tweet rendering: 3D and device motion

[arebe]

Troubleshoot inconsistencies with ondevicemotion sensor API. Firefox on Android seemed buggy and returned null objects instead of rotation values (though Chrome did return sensible values). As the user turns their device, the tweets should fluidly move as if they were in 3D space.

Potentially utilize a library like:

• Pixi.js - a 2D webgl renderer
• Phaser - HTML 5 game framework
• Famous js library for animations & interfaces (not as much doc)
