What is this?

Answer after the break.

A little alien?  I’ll give you a hint, it is lab related.  How about a ghost in the machine like the X-files title?  Last week I did some live-imaging experiments and couldn’t help but laugh everytime I saw this pattern.  What you are looking at above is a fluorescent protein filling up the nucleus from a human embryonic kidney cell.  I see a lot of these “faces” and like them, they keep me company in the basement.
