I feel empowered! Within two days of learning about the Design Recipe, I found an application! My husband wanted a formula to calculate how much "in-game" gold he'd need for his character upgrades, but the per-level costs of the upgrades weren't linear, and he wanted the sum of multiple upgrades. The long and short of it is that I was able to create a design recipe that helped me solve the problem!
With the elation I felt solving that problem, I can imagine how empowered my students will feel when they catch the vision of what this can do!
