You see a number in a black square. Hmmmm, lets square it ?

That gives us 3.541,899999997582772761

I'm sure i've seen that font before ... maybe in "Space, the final frontier ...."

Now if we google 3541 + star trek, we end up with the episode "The changeling".

Apparently, there is a thing called "Nomad" there ...
