Hi all!
I offer realization of the sign indicator on OpenGL. As such example an electronic clock can serve. The sign indicator is able to display all figures and some letters of the English alphabet. Possibilities: an inclination of symbols, scaling, a color choice. All is very simple, doesn't use textures and fonts.
Screen:
