We asked Lindi Wahl about Zero and One. Here is her reply:

My sisters and I had some fun ... and we have a video for you.
Basically, we decided that you could take away "zero", but the concept of zero is so basic that you could never really get rid of it.  You could stop calling zero a number, but it would still be exactly what it's always been -- nothing.

I AM NOTHING ... download the mp3 file

You can take away my name
I am nothing all the same...
You can say that I'm not there
But I never have been ...  I am nothing.

          I'm the absence, I'm the nil
          I'm the void you cannot fill...
          Call the numbers what you will,
          I'm platonic.  I'm ideal.  I am nothing.

You can take away my sign (my oval)
I exist outside of time...
Erase me from your number line
But that empty space is mine.  I am nothing.

          I'm the absence, I'm the nil
          I'm the void you cannot fill...
          Call the numbers what you will,
          I'm platonic.  I'm ideal.  I am nothing.

You can say I don't belong
In your cluttered counting song...
But when all the rest have gone
 5 4 3 2 1 ...  I am nothing.

          I'm the absence, I'm the nil
          I'm the void you cannot fill...
          Call the numbers what you will,
          I'm platonic.  I'm ideal.  I am nothing.
