E-wrench specializings in e-learning product development for both industry and education. We develop curriculum materials for the web using the Moodle Learning Management System. We also develop e-learning web pages using programming frameworks such as dot Net. On the non-web side we specialize in building e-learning virtual appliances. A virtual appliance consists of a virtual machine with an operating system and all application software in one package which allows the user to take home the complete learning environment they may find in the classroom. Currently our virtual appliance operating system specialization is with Ubuntu and we have both desktop and server appliances, including virtual Ubuntu servers running Moodle.
