Thinglink is a great way to get students to think about the impact of visual design as well as increase their visual literacy. The user uploads an image and places icons where appropriate. (For demonstration of deeper thinking, users should consider both the type of icon chosen as well as the "why" behind where it is placed.) Each icon becomes a link to a website, a pop-up of text information, or an already published video (such as YouTube) that you can play within Thinglink. Published Thinglinks have URLs that can be shared for others to see. While primarily a web-based tool, the iOS app for Thinglink allows you to record and directly embed your own videos.
