Padlet, formerly known as Wallwisher, gives you, in their own words, a blank wall and lets you put anything you want on it, anywhere. It, basically, allows one to build a wall using a certain number of characters. You can share the wall you build with others,upload video to it, and more.

Below is an example of a Padlet wall students and I created a few years ago. It explores Appalachian culture and language patterns.
