Though Tracey Emin isn’t generally thought of as a Light Artist, I thought I would include this image and link. She did a series of neon sign works, made to the form of her own hand writing with a personal message. Now she’s doing this cool thing where she makes an edition of a dvd with a looped video of the neon, that you can own for a very modest price. http://www.seditionart.com/tracey_emin
I don’t see it as a traditional transformation of space with light, though it could be if say it were the only light in a room. Still I think it’s interesting, and the juxtaposition between neon/signage (industrial, for consumers) and extremely personal words, is another way to think of Light Art for me.
