One of the large number of perturbations of the pillar wickstretcher.
These are made by simply deleting some of the pillar.  Ripples travel up
the pillar and break the pillar into clouds of slowly dispersing smoke.
Some ripples can reach the engine at the front, but appear to do no harm.
David I. Bell, April 1997
