From Wikipedia:

Degaussing is the process of decreasing or eliminating an unwanted magnetic field. It is named after Carl Friedrich Gauss, an early researcher in the field of magnetism.

Software engineers often spend hours a day engulfed in various technical aspects of computer science.  In this case, “degaussing” is the act of producing a small piece of art in order to free oneself from a technical mindset.  BZzzZT!
