1. A computer-controlled pyrotechnic matrix display device, comprising: a frame a backplate having a first surface and a second surface, the backplate disposed in the frame; an array of pixels, comprised of individual tubes set within the frame, arranged in a grid having at least two dimensions, each dimension having at least two pixels; an array of solenoid valves for controlling a flow of a flammable gas from a common input to termini of individual pixel tubes and directly into open air, the solenoid valves located on a first side of the backplate; an array of pilot light tubes positioned in front of the termini of the pixel tubes such that flammable gas exiting the pixel tubes contacts flames from the pilot light tubes and combusts, thereby creating a fireball, the pilot light tubes located on a second side of the backplate; a computer having control software to permit convenient scripting and control of all functions, which outputs control data through a parallel, serial, or USB port, said software controlling creation of designs in at least said two dimensions using said pixels; and a circuit board which processes incoming control data from the software and uses the data to actuate and de-actuate the solenoid valves with precise timing.

The devices according to claim 1 , wherein the frame, pixel tubes, solenoid valves and pilot light tubes together form a frame unit, wherein a plurality of the frame units are arranged and/or stacked to form a single screen unit, and the control software is able to adapt its output to address all the frame units and produce a single, coherent graphical and percussive display across the multi-frame units.
