Devices using glass bows

A pop-up having a collapsed and a popped-up state comprising a glass bow wherein the improvement comprises:

• a. a reflective and refractive surface having a retroreflection coefficient, RA (cd/lux/m2) (5°, 12°) of between about 0.2 and about 250;
• b. positioned between about 1 and 17 cm in front of said reflective and refractive surface, a shaped opaque object having a front and a back side, said front side of said shaped object facing away from the reflective and refractive surface and said back side of said shaped object facing said reflective and refractive surface as well as an edge forming a perimeter of said shaped object;
• c. said edge of said opaque object having an aspect about which a nimbus can be created,
• d. mounted on said back side of said shaped object, between about 5 mm and 2 cm from said aspect of said shaped object to have a nimbus and between about 5 mm and about 17 cm from said back side in the direction of said reflective and refractive surface is a point light source that shines on said reflective and refractive surface, and
• e. a power source in communication with said point light source to turn said point light source on.
