An example C program that demonstrates Text Mosaic Mapping with OpenGL/GLUT for ASCII-like image terminal art and animated matrix-like scrolling cipher code.

This version uses a Grid State rendering engine, insted of drawing arbitrary floating coordinates, and manages a rigid 2D array of character cells (like a real terminal).
- Pixel mapping for every character cell
- Cipher blend (for every character overlapping face image)
- Shifts active text color from green to image color
- Live Mutation: Even when the face is fully visible, the characters making up the image are randomly re-rolling (
grid_chars[x][y] = 33 + (rand() % 94)), giving the portrait a dynamic, crawling cipher effect. - Pixel interpolation (crossfading) between images.
The name says it all :P
