We bet your Nite Brites don't do this. Infernoptix designed the Infernoptix Digital Pyrotechnic Matrix to display a 12x7 screen of fire. They can display scrolling text, animations, mouse sketches, and burn dumb looking dancers. Ok, that last one was our wish, but it's certainly possible.
It may not be high-def, but it sure spices up a Bar Mitzvah.
