The Island Game was commissioned by Scottish Water to teach school children about water. The back end uses cayenne database abstraction, MySQL, XML with SHA encryption and Jakarta struts. This was a JAVA / JSP development. Toby Freeman developed the flash.
Won the CiB Scotland Award: Best Online Communication: 2005
