Overimposing multiple consecutive glyphs in real time.

[sammaelmose]

Hello, good people. I'm new here, and aren't sure this is the right place to ask this, so I apologize preventively. 

I have been asked to develop a very unusual font--one in which all characters overlap each other over a fixed axis until Space is pressed,  which would initiate a new group of overlapping characters. The way they envision it is something like a circular puzzle--each alphanumeric glyph would correspond to a particular piece of said circle, a slice, perse. 
Honestly, even though it is definitely not my first typographic rodeo, I admit to find myself a bit at a loss here.
All input,  ideas, suggestions will be greatly appreciated. Really.

Have a good one, you all.

Do you have an illustration of how the final result should look?
