Segment Display

The LED readout off the front of a rack unit — 7, 14 or 16 bars per cell, drawn as geometry rather than set in a font, because the thing that makes a real one unmistakable is the bars that are off: showing 1 still shows the ghost of 8. Around that: a recessed pane, a bloom on the lit bars, and light spilling onto the panel in proportion to how much of the display is lit. A plain value with a window of digits, or several captioned fields behind one piece of glass the way a multi-tap delay says what it is doing. Decimal points ride the cell before them, overflow truncates from the end the text is not aligned to, and the cells lean like every module in a rack does.
