IdeaPaint's official website reads:

IdeaPaint™ turns spaces into creative places. Use IdeaPaint to transform virtually any smooth surface into a high-performance, dry erase canvas and experience how big your ideas can get when you are no longer confined to the size of a traditional whiteboard!

While whiteboard paint has been around for a while (as has the paint that turns your wall into a chalkboard), the latest from IdeaPaint is pretty great:

IdeaPaint Clear's product description:

Think waaaaay beyond the whiteboard with IdeaPaint CLEAR, a new transparent top coat that delivers dry erase functionality to smooth surfaces of any color. Apply directly over painted walls, or even wood, to create a seamless think-space that matches any décor. With CLEAR, your walls won't look different, but they'll act different.

Their blog and youtube channel have some pretty great videos showing off IdeaPaint in business, home and classroom environments. Below is the announcement video showing off IdeaPaint Clear.
