TV Rock (Ulexite)

• TV Rock (Ulexite)
  Locality: Boron, California, U.S.A.
  
  Although it does not look like a stone, it definitely is a stone. It is called “the TV Rock” in western countries. From its name, the stone was probably first found after the invention of the TV.
  You might not be able to tell with this graphic image, but if you take a close look, you can see that the figure under the stone is emerging on the top surface of the stone!
  It was named TV Stone, because the top surface is just like CRT screen. But, as recent TV display is mainly of plazma or liquid crystal type, children might not even know CRT!
