+Open hands and let the delicate wings flap once. The disturbance
+ripples outward, changing the flow of the eddy currents in the
+upper atmosphere. These cause momentary pockets of higher-pressure
+air to form, which act as lenses that deflect incoming cosmic rays,
+focusing them to strike the drive platter and flip the desired bit.
+You can type `M-x butterfly C-M-c' to run it. This is a permuted
+variation of `C-x M-c M-butterfly' from url `http://xkcd.com/378/'."
