I have this headcanon that Spock’s ears wiggle when he’s super focused and doesn’t notice it happens. And obviously one day Jim/Bones will somehow manage to capture the moment in a holo. 
I want to do endless animations but damn, the frame count is not doing wonders for my platform! (Also I reused my steam animation because I messed up the new improved one one .. sigh)

And I’m still replying to your suggestions, I’m just slow!
