Alien lifeform, culture plate, or Leunig drawing?


I was tidying up one morning, when I noticed an unusual pattern on a common household item. I photographed it, and after a bit of enhancement it made an attractive picture. Can you guess what it was?

If you think you know what it is, send me a message. No-one has guessed so far.
