Abstract: Calcium reacting photoproteins are a class of self-illuminating proteins that emit light upon contact with calcium. Fluorescent Proteins are small proteins that change the color of light when excited. Fluorescent Proteins and Calcium Activated Photoproteins can be used to enhance, dazzle, amaze, startle, and otherwise entertain an audience by their direct application on to the audience, surroundings, the actors, or sprayed on settings as in the newer 4D movies. The disclosure comprises novel Coelenterazine compounds and methods of use, including a simple delivery device for the photoprotein to create unique and novel cinematic, theatrical, stage, movie and musical concert optical effects by their luminous reaction upon contact with surfaces that contain calcium. Calcium is ubiquitous in and on most surfaces and in the environment; it is this unique property of calcium that makes this a novel use of the photoproteins for entertainment. A generic formula of Coelenterazine as shown.

Abstract: Novel compounds in the classes of Imidazo[1,2-?]pyrazines and Imidazo[1,2-?]quinoxalines with a methoxy group modification show unique spectral properties when used as a substrate for luciferases and photo-proteins. Methoxy e-Coelenterazine, an Imidazo[1,2-?] quinoxaline shifts the emission wavelength by 80 nm to blue light compared to e-Coelenterazine, using Renilla reniformis luciferase. The novel analogues described here are useful in combination with fluorescent proteins to create BRET (bioluminescent resonance energy transfer) and for other luminescent assays. In addition these novel compounds can be used to enhance, dazzle, amaze, startle, and otherwise entertain an audience by their direct application on to the audience, surroundings, the actors, or sprayed on settings as in the newer 4D movies.

In addition these novel compounds can be used in novelty items and for entertaining purposes to create different light emitting colors using the same luciferase or photoprotein.

Abstract: A furniture pull-down shelf has first and second opposed lateral webs delimiting a shelf receptacle. First and second pairs of pivot levers are pivotably secured on first and second opposed furniture sidewalls and on the first and second lateral webs and define first and second four-bar linkages. The first and second four-bar linkages transfer the shelf from a stowed position inside the furniture into a lowered access position. An operating element is connected to first pivot levers of the first and second pairs of pivot levers. It extends in an initial operating position along a front side of the shelf receptacle. When pivoting the pull-down shelf into the access position, the connecting element moves from the initial operating position into a downward open operating position.
