# Cracktro (クラックトロ)

> A short screen bolted to the front of cracked software as a group's calling card. An oversized group name, text scrolling without end and a run of greetings turned the home computer display into a stage.

- IndexStyle No.308 — https://indexstyle.org/styles/cracktro
- Kind: Style · Family: Digital Art · Era: 1980s-1990s
- Mood: Technique, Rebellion, Exhilaration
- What this family collects: Practices that treat the computer as material rather than tool, many of them imposing limits on polygons, file size or hardware and competing inside the boundary they chose.

## Defining characteristics

- Text scrolling endlessly across the screen
- Bands of color running behind it
- An oversized group name held at the center
- A run of greetings naming other groups

## Best used for

- Bolting a short screen to the front of something being passed around, to give the group's name
- Packing a burst of sound and image into an executable with a small size budget

## Composition recipe

- Typography & lettering: Monospaced bitmap letters running the greetings along the bottom without a break
- Layout & structure: Hold the oversized group name at the centre and keep the effect moving around it
- Material & texture: Patterns generated from formulas and a short looping tune, built with no asset files

## Colour

Read off the reference works below, so a direction rather than a fixed palette.

- Ground: #e6fbfd
- The colour it is remembered by: #3a80c5
- Text and outlines: #0a0f13

## What to avoid

Line up the effects but drop the name and the run of greetings, and the calling card is gone, leaving only a short piece of animation.
