Produce four original images in the visual language of Oberon System Interface, a layout from Platform Screen Languages, 1988–.

## What to make

Make the kind of thing this style 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 images.

## What has to be visible

- 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

Someone who knows this style should be able to point at each of these in the finished image.

## How to build it

- Layout and structure: 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
- Material and surface: One bit, black on white. Single pixel rules, no shadow, no rounded corners, no greys and no colour. Mark the insertion point with a hook
- Colour: #FFFFFF carries the ground, #808080 is the colour the style is remembered by, #000000 holds text and outlines. Read off real works, so treat them as a direction rather than a fixed palette.
- What it should feel like: technique, calm, rebellion

## What goes wrong

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.

## Across the four

Keep every cue above present in all four. Vary the framing, the scale and the arrangement so the set shows the range this style covers 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 language described above.
