# Oberon System Interface × Terminal UI — composed image prompt

# Oberon System Interface carries the structure and Terminal UI appears as the accent.
# Style descriptors only. This prompt names no artist, studio, brand or work.

Produce four original images that take their structure from Oberon System Interface (layout, 1988–) and their accent from Terminal UI (style, 1970s–).

## What to make

Make the kind of thing Oberon System Interface exists for: designing a workspace that gives up overlapping windows, where placement is decided by only two moves: which track, and where in that track, or giving a product a command list the user can rewrite, held as an ordinary editable text instead of a dedicated menu component. Choose one subject and hold it across all four.

## Structure comes from Oberon System Interface

- Nothing overlaps: the display is cut into vertical tracks first, then tiled top to bottom inside each track
- A narrow track on the right holds a log above and a text of commands below, with the wide working track on the left
- A one line title bar across the top of every viewer, carrying the document name and commands such as System.Close as plain text
- One bit per pixel, black on white, with borders drawn as single lines and no shadow, rounding or grey

Composition: Cut the display into vertical tracks and divide each track horizontally. Never overlap. Keep a narrow right hand track for the log and the command text and leave the left wide. Give every viewer a one line title bar. Type and lettering: Set commands in the same face and size as body text. Name them M.P and spell them out as words, Copy and Rename rather than cp and rn.

## Accent comes from Terminal UI, used sparingly

- Single phosphor color on black
- The monospace grid
- A blinking cursor
- Scanlines and glow

Let one material quality come from it: One phosphor hue on black with scanlines and bloom added sparingly.

## Colour and feeling

Build the ground on #FFFFFF, carry the structure in #808080 and #000000, and let a single accent come from #00a800. These are read off real works, so a direction rather than a fixed palette.
Feeling to carry: technique, calm, rebellion.

## What goes wrong

- Oberon System Interface: Copying the tiling without the rule that any text on screen is executable forces the menu bar and the buttons back in, and all that is left is a cramped layout.
- Terminal UI: Heavy scanlines and flicker cost legibility and the atmosphere ends up beating the speed that made the tool worth using.

## Across the four

Keep the roles fixed in all four. Vary the framing, the scale and the arrangement so the set shows what this pairing can do rather than four versions of one picture.

## Constraints

- Do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work.
- Do not reproduce the composition of an existing work.
- Produce original compositions in the general period languages described above.
