Currently the applets need
Cinderella (free download from Cinderella.de)You can then use Cinderella to save as an html file, and once opened when connected to the web, save this as a webarchive on the machine you want to use it on. This complication is due to websites not handling files in non-standard format such as .cdy) Please contact me if you have any trouble or if you want a version that will run independently on a tablet or iPad: john.mason @ open.ac.uk |
