The properties that exist now:

fishing_rod: cast
clock: time
compass: angle
bow: pulling & pull

Any item that can take damage gets: damaged & damage
And on all items: stack_size

All properties are mapped to a float range 0-1.

Nothing of this is final! =D (And the carrot on a stick is just a demo!)

Awesome feature! This is going to be really helpful, but wouldn't it result in huge resource packs?

Seems like a way to render breaking items!

Second comment too.
