We have had less activity on the blog because we were finalising the first full draft cbook for classroom trialling. Last year we made two cbooks, one on congruence and one on figure transformations. We have edited and extended the former and it is now up for a final polish and translation. If you want to have a look (Java is advised, although an HTML5 version, of course, is made concurrently) by clicking here (log in with username ‘eng1’ and password ‘pass’). Note that there are several cbooks, in different phases of development, so also very unpolished ones. We did this to show the developmental aspect of the project.
