The latest version of expresser was released today (download migensystem-1-2121a.zip).
After several cycles of improvements and testing with students this version, apart from several bug fixes, demonstrates:
- Improved tile creation (tiles are dragged from the toolbar and placed on canvas)
- Revamped property list to make more apparent:
- repetition of the base shape
- shapshot as button to open property list
- Expression for construction
- see the properties of the base shape of patterns of group of tiles
