Write it, Say it, Slap it

or in this case ... Stick It, Remember It and Peel It

There are a number of "sticky notes" applications available for your pc or mac. Intriguing stuff. Here is one of the newest. And it's not just for to-do lists anymore!! (that's a different app altogether)

This one from LinoIt

You can include pictures and even movies and share among friends or coworkers.
