I almost forgot this weirdly beautiful image of hot glue from my installation of Numinous at Central Washington University.
Before leaving campus, I played with a black light the administrative assistant brought to work for me to use, as she said, to “imagining the possibilities.” What I imagined is a white box gallery within a dark gallery—and curlicues of hot glue soaked in blue purple light. Use of flashlight to enter recommended. And music, too, possibly Philip Glass. Eeeeeeerie!
The purple-blue glow is the result of phosphor, which is essentially any substance that emits visible light in response to some sort of radiation. A phosphor converts the energy from a black light into visible light.
