Small responsive easter egg. Do with it as you wish.

/*
  This is pretty much the smallest you can make the firefox screen without programmatically setting the width.
  Chrome and Safari prevents you from going below 400px. An iPhone is 320px, and the smallest Android about 240px IIRC.
  The site is pretty much useless like this, so... have an egg.
