PixiClip is a cool new tool for educators or presenters that provides a whiteboard that can be marked up during a presentation. Images can be uploaded, allowing the presenter to draw and type on the image. While adding elements to your PixiClip, you can talk and record a video of yourself talking. Recordings can be shared via social media or included on a webpage.
The tool is in beta now, with new mark-up tools added in the future.
