BROOKLYN - Two Brooklyn artists are living in a giant hamster wheel for 10 days to display the importance of cooperation in relationships.

Ward Shelly and Alex Schweder built the 25-foot wooden structure and fixed furniture on the inside and outside. The artists are perched on opposite ends of the wheel, 180 degrees from each other. This forces them to carefully coordinate their movements because when one walks, the other must walk in the opposite direction to accomplish getting anywhere.

Schweder says they need to communicate to accomplish something as simple as walking to a chair. He says relationships are often about cooperation and keeping an environment stable with communication.

Both artists say the experience is difficult, but they are taking the challenge on together and learning about the nature of friendship in the process.
