Lino It is a free service that allows you to create a canvas of online multimedia sticky notes. In addition to basic text, the sticky notes you place on your canvas can contain videos, images, and file attachments. Unlike some similar sticky note services, Lino It allows you to alter the size and color of your fonts. You can use Lino It's built-in calendar tool to set due dates on your sticky notes.
To use Lino It, you have to register for an account. Once you've registered you can create as many sticky note canvases as you like. You can make your canvases and notes public or private. If you choose to make a canvas public other users can add sticky notes to it and read all of the notes on it.
Applications for Education
Lino It is very similar to Wall Wisher which I've used a few times this year for brainstorming sessions and to create collages of student-contributed information. Those same things and more could be done with Lino It. Students could use Lino It to brainstorm on collaborative projects then outline tasks necessary to complete those projects. The tasks can be assigned due dates on each sticky note. Attaching files to Lino It stickies allows you and your students to post PDFs or other documents that may not be available online.
