E.V.G. Lab

Symbols and licences

Exercises in the lab will have cards with symbols: a picture and a label help to understand the task and to answer without words. We take the symbols from three open sets. This page lists the sets, their licences and their authors, as the licences require.

What these licences cover

The licences of the sets apply only to the symbols themselves. The lab's code, its exercises and our texts are not covered by them. The labels of the symbols in the different languages were written by the E.V.G. Lab team.

Licences checked on the websites and repositories of the sets: October 23, 2026.
