…all updated examples to this environment both for visual appeal, but also to make it clear that these new examples are separate from the old examples. Removed particles. Made tracked hands actual hand models. Added basic illustration of how to add hands dynamically. Added comments. Removed unnecessary schema examples because position and rotation are tracked by default. Added hand model assets. Removed lighting,sky,grid,ground--all now handled by environment component, making the example less distracting. Changed avatar template code style to be more visually clear (no need to add emphasis to the avatar geometry with newlines). Changed avatar proportions so that hands are not swallowed by them, and changed proportions slightly to make them somewhat less dorky looking--I also suggest this modification across all examples to create a new coherent visual style for current examples, although I'm open to better options. Added joystick movement controls and flying ability via aframe-extras.
