well, if you think about it the lens starts in the center of the business
card and moves out in an expanding spiral until it reaches the end of the
cd.  Presumably, this circle has a radius equal to the shortest distance
from the center which would be the short width of the business card.
Basically its a circle that fits in the rectagle; it will never hit any
blank space.
