Here's one. I initially mistyped him as Ni. Part of the reason was I thought I saw raised outer edges. Maybe it is actually an Si signal, such as dancing brow? But the inner ends of his brows don't noticeably rise, only outer.

Also, how is his hand not plateu velocity? Is it because his head is also moving, making it coordinated and therefore Fe instead of Te?

@fayest42 I don't think it counts as a "mixed" signal because there's no such thing as "Si blinking eyes", but yes, it can be confusing because there's "Ni unblinking eyes" (but you don't need all the signals to be checked, afaik).

@janie Who's this? Would you mind sharing the video?
 

 
Edit: fayest is right

The outer edges of the eyebrow area are continually raised upwards by default, elevating the brow off the eye area - (Codifier)

Oh, ok, it's around 4:50!
Doesn't look like plateau velocity to me:

As a direct reflection of Te’s streamlined psychological attitude, its gesticulations are equally marked by briefness and quickness of execution. They will carry a different tempo than Fe’s gestures, being snippy in their delivery and earlier in their repetition.
[...]
It will nonetheless retain its cascading and unbroken flow, transitioning from one deduction and expressive motion to the next with a nearly uniform velocity, whether that velocity is fast or slow. It will not oscillate between halt and push as Fe-Ti does.

I think in 07:57 - 08:07 you get the idea.
