When I saw these I thought they were awesome! I love all the possibilities you can come up with using these huge letters. I have a large dry erase board on a wall in my home and you can create all kinds of words and phrases with large letters. The question would be how to organzine the letters so they are easy to find and use. Now that is one I haven't figured out.
I can't get the link to work so I attached the picture from their website.
