Reminds me of some 'drawing with light' photography that was very popular about 35 years ago.

Back then the drawing was done with pen lights and usually involved a model. The drawing was done around the model with a very long exposure in a complete dark room. Once the 'drawing' movements were finished a flash was used to illuminate the model to complete the shot.

An example would be 'drawing' angel wings behind and a halo above the model. The flash makes the model visible as in a normal photo but the wings and halo would also be very visible in the image.
