Round 1: Warmup

A lightcycle from the movie Tron.

“I tried to picture clusters of information as they move through the computer. What do they look like?

Ships? Motorcycles?

Were the circuits like freeways?

I kept dreaming of a world I thought I would never see.

And then, one day, I got in.”

—Kevin Flynn [Jeff Bridges] (TRON: Legacy, Walt Disney Pictures, 2010)
