Reticles

Reticle thoughts:

Reticle is a fun word.

Animation draws the eye and makes pixel-thin reticles much more noticeable. I'm reminded of how some video games will 'bounce' a waypoint marker to remind you about it. 

Positioning the reticle a little in front of the target (as opposed to flush with the target) adds some subtle depth that I find interesting, but might add clutter in busy scene. Worse, another object might pass between a target and its reticle.
