# Motif carries the structure and Oberon System Interface appears as the accent.

Produce four original images that take their structure from Motif (style, 1989–) and their accent from Oberon System Interface (layout, 1988–).

## What to make

Make the kind of thing Motif exists for: rebuilding a UNIX workstation era application for an exhibit or a technical write up, or building instrument or CAD controls where pressable and unpressable must read as relief rather than color. Choose one subject and hold it across all four.

## Structure comes from Motif

- A gray face lit along its top and left edges and darkened along its bottom and right, so every part appears raised
- While a control is held down the two edge colors swap and the part sinks
- A thin rectangular ring is drawn around whichever control currently takes keyboard input
- Scroll bars are square cornered rectangles with a triangular arrow button at each end

Composition: Windows are cut into beveled rectangles and controls are packed a few pixels apart; there is almost no breathing room, the screen is filled with operable parts. Type and lettering: A small sans at one fixed size, labels held to a single line, no letterspacing and no ornament inside the text.

## Accent comes from Oberon System Interface, used sparingly

- 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

Let one material quality come from it: 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 and feeling

Build the ground on #D3D3D3, carry the structure in #B4B4B4 and #5F9EA0, and let a single accent come from #808080. These are read off real works, so a direction rather than a fixed palette.
Feeling to carry: technique, trust, calm, rebellion.

## Where they fight

- Motif and Oberon System Interface both belong to Platform Screen Languages, so the difference is small. Push the roles further apart than feels comfortable.

## What goes wrong

- Motif: Replacing the two hard edge colors with a soft drop shadow kills the flip that signals a press, leaving decoration that merely looks raised.
- 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.

## 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.
