This is something which also has an application to paper modelling.
Over the years, I've occasionally done some work involving lettering and I've been doing some again, lately.
I've made two YouTube videos of animations using letters and uploaded them in the last few days.
This one is a computer animation:
Stop Motion Letter Board Titles, Kaleidoscope 2 - YouTube
This one is a stop-motion animation using a letterboard. It's best viewed at 2x normal speed:

It's not a shop, that's just the name of the domain.
For many years, I've used TeX for typesetting and MetaPost for graphics. I've also used METAFONT, which MetaPost is based on. For some projects I have in mind, I've been wanting to modify some METAFONT fonts and use them for displays. MetaPost provides a way of extracting the outlines of PostScript fonts, including METAFONT fonts that have been converted to PostScript, which is what I need as a first step..
I've only just started working on this. My results so far are in the attaached files.
