If it's the thing on the screen, then halos provide a way of interacting with the object. If the thing on screen is a presentation of the "real" object, then halos can be looked at as a way of interacting with the presentation, or (not exclusively) as a simulation of interacting with the object, and that simulation is also presented in a certain way.</div><div dir="auto"><br></div><div dir="auto">When the objects are presented to us as text, we know to think of that as a representation of the "real" object, which is some value stored in memory. When the object is a shape or something similar, things get hazy.</div><div dir="auto"><br></div><div dir="auto">So what is a Morph? Is it a thing drawn on screen (even if it has other things drawn on top of it, so maybe not visible at the moment)? Or is it what the the thing drawn on screen represents, an abstract thing-that-could-be-drawn-on-screen-in-a-canonical-way? (What is a Morph that has been collapsed? What is a Morph that hasn't been drawn yet? Can they have halos? What would undrawn halos on an undrawn Morph be for?)</div><div dir="auto"><br></div></div>
