LTR Principia is a cheerful regular-to-narrow variable display serif headliner with very pretty italics. It has a single weight suitable for most applications. Illustrative and playful, it is aware of most rules but not always bound by them. The width axis is useful for fitting words into small boxes.

Fits headlines to boxes and titles to books! When the format is given, and the copy can’t be cut, the type can be tighter.

This one won a TDC thing once.

A brutalist serif, a reviewer observed. But it also has all sorts of silly things, nice curves and ball terminals.

Arrows & fish: with variable width. Italic fish swim one way, the uprights in the other.

Small books: not exactly LTR Principia but this is where those pointy contrast ideas popped up.

Even in a simple text editor, Principia looks good.

Even in a simple text editor the widths of the non-variable OpenTypes invite playful solutions.
