Is it a bird, is it a plane?

OK what is that fascinating pixel (1) near the STC building that is (2) out of synch with the clearance lights?

Just wondering.

I don't know, maybe Alex or Lertin left us a memory there.

That's just a stray pixel, and since it's only in one frame it blinks with the lights. No mystery here...

I don't know, maybe Alex or Lertin left us a memory there. 

The STC is one of Flemms few adventures into architecture, note the distinctly cubic shape .
And the secret message is encoded in the lit windows instead, but I forgot what it was and how to read it.
