There’s a seriously cool green laser on top of a Siemens building in Adlershof in Berlin.

  1. As an astronomer I would better say:
    “seriously unnecessary light pollution” :-)
    … or is this laser used for any scientific purpose?

  2. I looked at it closer today. I don’t know if they change the direction every now and then, but today it was pointing pretty horizontal. I don’t think it’s useful in any way, it’s just for show.
