Ah, I knew that picture was familiar! I was guessing it was from Fate/Hollow Ataraxia, but I didn't want to jump the gun. Type Moon is made of win indeed.

I pretty much agree with you on that Saber doll. With animanga, and most art in general (I'm not including artwork that depicts human figures realistically) can pull off unrealistic character designs, life-sized dolls can't. Heck, just looking at it makes me wonder if a person could live with Saber's crazy anatomy in real life! Yikes, I don't even want to imagine it (or the possible anatomy, since one semester of it burnt me immensely).

Eh, I found the mathematics icons from browsing around the iconist's icon journal, but this post has a few quirky ones. I really like the integral one (the log (cabin) + c one).
