elza: serif meets ball terminal... I found out the Germans actually have a word for this: 'Tropfenserife', which roughly translates as 'teardrop-serif'.

( short starter panel
) short end panel
[ long starter panel
] long end panel

It's just a simple & elegant solution utilizing 4 parallel lines.
See how neat the letter 'B' is formed by 6 rectangles.
