Lighting is everything. Just ask the actor, the painter, the sculpture. If you don't have the lighting right, then your work of art can be just ordinary. Now imagine you are working with an entire room, or an entire building, or an entire city! Lighting architecture requires a special knowledge and appreciation of natural and artificial lighting.
Implications - Glowing buildings and sculptures are something that we will see a lot more of in the near future. Lights grasp people's attention and advertisers can use this idea to showcase their ads on the sides of buildings by using lighting. Nightlife thrives in the warm months and people will be outside to notice glowing ads.
