Cargo was a project we worked on with Golem Foundation that never launched. The original idea was a universal file system with some knowledge base concepts like multiple paths to any file. Large groups of shared files were thought of as forests, while the atomic unit was the container, a file or group of files with a manifest carrying metadata.
It was probably too ambitious, with apps for every platform, too similar to existing services like Dropbox, and assumed users would actively want to organise their own files. It made it to a few prototypes and then was killed — but some of the team went on to build Octant.
As the main Cargo app was intended to both work as an integration into the user's file system, and as a web-based platform, we created icons for forests, containers and shared files that would work clearly right down to tiny native filesystem list views. Stuart Wade worked with us to create a series of dark and light mode spot illustrations to be used throughout the apps.
