Those paintings were created during the long nights in Olafsfudor, Iceland 2017-18. 

Iceland is a volcanic island and the sand on the beaches is black.  I used the sand found there to paint abstract paintings during the long nights.  The mountains were stunning with black and white strikes, the sea gray and, during the short hours of light, the sky often was changing between various grays, blues and reds.  I wanted to respond to the long hours of darkness and the magnificent phenomena of northern lights by giving my paintings a visual experience when the lights are turned off as well.  I painted with invisible glow-in-the-dark pigments on top of the paintings so each canvas can be seen both in light and in darkness.
