Activities/Labyrinth

Labyrinth

Download is available from the Sugar Labs Activity Library.

Labyrinth is a lightweight mind-mapping activity based on an Open Source project called Labyrinth. It allows creating mind maps from a mixture of text, freehand drawings, and images from your Journal (image support currently broken for XO 8.2 due to Rainbow related issue). There is an infinite sized canvas for your map that can be panned and zoomed while you work. Maps can be "Kept to PDF" for uploading to web sites, sharing, and printing by others who may not be using Sugar.
