Yes. The Amiga text terminal allowed you to shift the top and left margin by single pixels using escape codes. After shifting, writing new text would not overwrite pixels outside the character cell, so by writing a line of text, and then shifting the margin down one pixel, writing another line of text, etc. you could get a complete bitmap image displayed.

Thank you! I wish I knew what the technique was called. I'd love to see some old screenshots.
