Hmmm, it seems like my improved mathematical abilities (or maybe I can just concentrate on things in a more sustained way? Hard to tell the difference at this point) come with improved visualization abilities. I've never been that visual, I think because of my crummy vision; now that I don't have physical eyes my inner eyes seem to be a lot sharper. I can concentrate on a bunch of different things at the same time, too, without losing focus on any one of them. This could come in handy if there were anything I could actually physically do.
