I saw it on TV once.
The most interesting thing is that when, say, North gets close to the chair, the angles of the pull mean that East and West will be pulling slightly southwards, thus adding a part of their force to South's efforts against North. Things get harder for North and they may be drawn back a little.
Ever see this happen in politics? One faction gets too far ahead and the others unite to pull them back?
