JP Trostle continues his exploration of chaos and light with “Signals,” on display at The Atomic Fern throughout the fall. A followup to his solo shows, “Luminous Creatures” and “Light Cycles,” the artist once again delves into an examination of the happy accident, and imagines how solar wind and atomic decay might look if humans could see that far into the spectrum.

Reception: Friday, October 19 at 6 p.m.
