IdeaPaint: Erasable wall paint
IdeaPaint turns virtually anything you paint into a dry-erase surface and any room into a hub of creativity and collaboration. Well thats what the nifty looking website says anyway.
The application in an office space is obvious, but I think this would be great as a home application. Especially for the new homes in Boise Idaho.
Make a room, cover it in this stuff – and you have a free-for-all room where you can let the children (or inner children) vandalise to their hearts content. Excellent for creative development of the brain, we say.
