The first artist is Brian de Flores whose art and communication can be found with a Google search. His work covers all types of light language from Angelic to dolphin, Pleiadian, Sirian, Arcturian, and many more. His visual art is superb.
The next I've included is Bala Deva'S work Which I came across from the book review Living Light Language. He does sculptures, paintings and writing glyphs.
I believe some of the Aboriginal art may also be light Language. As this is a work in progress, I'll be adding to this aspect to include early human art.
