Freyer (http://www.mice.com) uses the imagery of Trojan mice, (small, well focused, and easily manoeuvrable initiatives focused on building creative relationships between existing systems and components) to reflect the complex adaptive systems theory principle that change is not incremental and small inputs can have unexpectedly large return. I use this “Trojan mouse” (gift with a hamburger meal) for engaging students in discussions about the imbedded health related issues of marketing to children, fast food consumption, and the effects on workers’ health in outsourcing manufacturing to countries reliant on child and prison labourers.
