It Wandered In From the Wastes

This picture's title (Tesla, inventor of the glowing pearl) is an unnecessary irony. The "glowing pearl" is actually supposed to be a ball lightning. It is a reference to one of thousands rumours about the famous scientist. It has it that at a party in Tesla's house he not only showed to all guests a ball lightning but also took it in hands and cut it in half.
