How: pathways to someplace

I find a picture, one from someone whose work I have enjoyed a few years — they’ve an interview in a magazine I have no use of otherwise, but I buy it. Read it. Regret having bought it, since the interview is primarily about the “how” of the work.

So I create this word stack:

light art
optical fiber
Heinz Hajek-Halke
Martina Corry
gottfried Jager
MMX Gallery
Katharina Sieverding

which reminds me, and may lead you toward the meaning of the work without regard to the way it was made.
