Great update.
Nice to hear the thought process behind developing animated battle scenarios - very cool idea, and in 3D holographic funkness

I gotta admit, I'm on board with everyone else who thinks that Parson's memory has been adversely affected.
I mean, this is Parson.. a dude who's spent presumably many many years playing tabletop war games, designing them himself at points. He's a smart dude, and good with maths - for example, working out odds/ratios/percentages etc, albiet, admittedly with the Bracer - BUT, he knows how to use the bracer to figure them out. IE, he knows which calculations to use the Bracer for.
He knows maths, tabletop war games RUN on maths. Anyone, who is remotely interested in math, who remotely likes math, will know at least what Trigonometry is for. May not remember the formulas, but will at least know that it's about triangles.
So, for Parson to "wonder" if it's something to do with triangles, then immediately second-guess himself - Well, to me, that's something VERY important to worry about...
