Assets Repo

This repository exists to keep all assets for Chaostreff Osnabrück e.V. and their hackspace Rabbithole in one place. Please use the vectorized versions whenever possible. Some things might be work in progress. When adding new things, please make sure to choose self descriptive names and folders.

License information follows the REUSE specification. See REUSE.toml for the full details. A summary:

• The DIDAY logo embedded in diday/events/ is © 2026 Stella Schiffczyk, licensed CC-BY-4.0, from DI-Day/website.
• The pixeled background in diday/events/ is © 2025 MultisampledNight, licensed CC-BY-4.0, from DI-Day/creative-identity.
• The Chaostreff Osnabrück e.V. logo embedded in diday/events/ has no open license (all rights reserved). If you reuse or adapt these graphics, you must replace or remove the Chaostreff Osnabrück e.V. logo.

Marp slide deck for the DIDAY talk given at Digitale Woche Osnabrück, 2026-09-24. The talk's own content is © 2026 Nils Israel, licensed CC-BY-NC-4.0 (non-commercial). slides.md also quotes third-party sources directly; those quotations are individually referenced in-slide, not separately license-annotated. Fonts and the Chaostreff logo are symlinked in from fonts/ and chaostreff/logo/ and carry those directories' licenses. Bundled third-party assets:

• The DIDAY logo/favicon are © 2026 Stella Schiffczyk, CC-BY-4.0 (same source as diday/events/).
• assets/icons/mail.svg is from Lucide, © Lucide Contributors, ISC.
• assets/icons/mastodon.svg and matrix.svg are from Simple Icons, © Simple Icons Collaborators, CC0-1.0.
• assets/twemoji/ is Twemoji, © Twitter, Inc and other contributors, CC-BY-4.0.
• assets/media/nichts-zu-verbergen.jpg is © Alex Snaps, CC-BY-2.0 (Flickr); see the in-slide credit.
• assets/media/diday-39c3.jpg is a still from the "Die Känguru-Rebellion" talk at 39C3, via tube.funfacts.de, CC-BY-NC-4.0 (non-commercial) - see the in-slide credit.
• assets/media/map_events.jpg is a screenshot of events.diday.org (built and run by CCC Flensburg), which renders its map with OpenStreetMap data, © OpenStreetMap contributors, ODbL-1.0. The screenshot itself is © Nils Israel, CC-BY-NC-4.0 like the rest of his own talk content; the map data within it is ODbL-1.0; the platform's own content/branding is not covered by either license.
• assets/media/rabbithole-left.jpg and rabbithole-right.jpg are crops of rabbithole/inside/long-exposure.jpg, © Tim Klausmeyer, CC-BY-NC-4.0 (non-commercial). This overrides the general "pending" license shown for rabbithole/ in the table above - that one photo is externally licensed, not Chaostreff Osnabrück e.V. all-rights-reserved.
• The deck also displays the Chaostreff Osnabrück e.V. logo (see above, no open license).

The font used in our logo is DejaVuSans Mono. Because not all systems have this font installed, text should be converted to paths so it renders the same on all machines.
