Imagine a nanomachine which goes into your brain and boosts your cognitive and creative capabilities. Imagine one which creates whole new characters in your mind, to be used in games and entertainment. Now imagine it goes out of control and overflows your mind with endless worlds full of characters…
More of a thought experiment than a proper story, this is nonetheless a very entertaining piece of flash fiction with a clever, though slightly predictable, ending.
