This is an example with one direction out of 4 different writing directions. In this case the direction is from bottom to top. Once you've determined the writing direction, with the arrow, you can read the glyphs themselves from any position.

The text says: F IS FOR FUTURE.

In another uploaded document there are all the new glyphs I designed, to be included within an alphabet meant to form words intended to be read from all directions. This is invented for a rather distant future where it will be useful to read words upside down as well as right side up or from right to left as well as left to right.
In other words, this is meant for a microgravity (or zero g) environment, in spaceships or space stations (or in between them).
