You are exploring a universe beneath the streets of New York City. You hear a strange scraping noise. There is a dim light. The odor of limes fill your nostrils. In your left hand is the book Strange Brains and Genius.

You are currently 197 feet below the city.
You pick up a balalaika on the tunnel floor and begin to play. As the music evolves, several tree roots seem to gyrate, their tendrils intertwining like stripes on a candycane. Shadows begin to spring up as if they are living creatures. Soon, the only illumination comes from green and red lights emitted by bioluminescent bacteria coating the tunnel walls. It reminds you of Christmas.

Click on either angelic light to continue your journey. Do not despair. If you ever find the golden calf, let me know.
