utopias and dystopias --
"Move" (in your mind of course) to a utopia or dystopia of the future.
Imagine every possible aspect of that society, from big picture to tiniest detail.
Spend some time sketching it all out in your mind, then write a 1000 word letter back to our world, to warn us about the dystopia or get us excited about the utopia. The audience is a citizen of our world, can be fictionalized as a friend, family member, newspaper, or the younger self of the letter writer.
Have fun whichever one you pick.
