Scraping Ice, Thinking Chess

Scraping ice from the driveway, thinking about chess.

MOBIUS DRIVEWAY

Every snowflake is unique and special.
Every driveway is unique and special.
Every snow shovel is unique and special.
Every shovel full of snow is unique and special.

The Mobius Driveway is a driveway in which no matter what end you start shoveling, you never reach the end, because by the time one end is shoveled, the other end is full of snow.
