Yay, time for the riddle!  You know you like to be frustrated once a week; admit it.

This week’s riddle should be fun.  I know I had fun making it.   Then again, I have fun making all the riddles.  Anyway, I don’t expect it to remain up long, so get your guesses in quickly.

Ready?  Okay, the riddle subject is an object, and here are the clues:

This is a singular object, although it has lots of company.

It’s fairly common to find objects like today’s subject, but exciting nonetheless.

Then again, today’s subject is like none other.

It was not known to ancient man, but was well-known by modern times.

Today’s subject is famously two-faced.

Sometimes you see it, sometimes you don’t.

It’s unusual appearance is caused by something very famous.

It has an uncommon shape for what it is.

Everything is black or white with today’s subject; no shades of gray.

That should be enough to get you going.  If this riddle stays up longer than 20 minutes, I’ll be surprised.  Still, I wanted to give you a nice, easy, fun riddle to play with today.

You know where to find me.

Everybody loves lurking spiders. Right, Trudy?
