When a fan blade starts to spin, as it spins faster, a dark
'virtual' blade start to form and spin. As it spins faster, the
'virtual' blade starts to disappear. As the fan blade spins even
faster, the 'virtual' blade starts to form again. However, this
time it spins much slower and in the opposite direction of the
one formed earlier.
