What if students received a sweet visual effect in Canvas when they submitted an assignment? Asana has a similar feature when you mark a task done. A unicorn or something will shoot across the screen. Instructors and developers could toggle the effect for different assignments and either pick a specific effect or let a random effect occur. Imagine a panda flying across the screen! Larger scale effects could be attached to larger assignments like final projects.
This idea has been developed and deployed to Canvas
