Legood is a set of graphic objects for making diagrams in the shape of Lego bricks.
It is provided in the Scalable Vector Graphic format, made with Inkscape. SVG should be portable enough to be opened in many other softwares (Illustrator, Corel, Gimp, LibreOffice, any browser...).
Legood is covered by the CC-BY license, so when making diagram with it, you must indicate its origin. For instance, by adding: "(made with Legood)".
