The Tengo alphabet was invented by Bob Weiland during the month of October, 2009. It started out as as "Tenctonese", the alphabet featured in the old TV series, "Alien Nation". The script went through several iterations until it arrived at a script quite different from the original.
Tengo iterations are demonstrated in this pangram: Pack my box with five dozen liquor jugs.
It seemed too contrived to construct the 2nd half of the alphabet as the mirror image of the 1st half of the alphabet. Rearranging the letters generally by sound groupings resulted in:
There seemed to be too many lines above and below the letters. Placing the lines into the letters themselves resulted in:
This seemed quite nice. But the some of the letters were drawn out too much. Shortening some of the letters, and altering others, resulted in the following. This script is different enough from the original to warrant a new name.
The ascending and descending tails going in different angles causes this alphabet to lack the symmetry of the Tenctonese derivation 3. Synchronizing the tails in one direction adds back some strokes into the letters, but it looks more aesthetically pleasing. So the following is the final version.
The font font was also entirely redrawn.
All human beings are born free and equal in dignity and rights. They are
endowed with reason and conscience and should act towards one another in a
spirit of brotherhood.
