It depends.
In the cases of subjects that I have an interest, I can be quite interesting to those with a clue what I’m talking about, and very tedious to those that don’t.
In general conversation, how interesting I am depends on my mood, my energy level, the amount of time I have, and the interestingness of those around me.
Total size of footprint: Uncertain, as it can shrink and grow quite rapidly.
I am uninteresting both here on the boards and in real life.
What?! And risk creating boredom by belabouring the obvious??!!

BTW, “easily controllable” is a term that is open to interpretation. Firstly, if one is only considering crystolographic bi focus microlithographic “imprint” as a primary basis, the focus length is limited by the diffraction co-efficient of the undoped matrix. Sheesh!!
Everyone knows that!

Secondly…
I have a friend who helps me on various projects in my basement shop… He considers most of the stuff quite boring… he has learned over time, to take advantage of me saying "“now… this next part may be a little complex…” as a good opportunity to put on the Haz Mat suit…

(Last “this may get a little complex” involved microparticles of molten glass moving as supersonic velocity… ok YES an explosion…but of very limited area)
