This wall clock is so much fun, the dry erase wall clock from designer Ricardo Saint-Clair. Although normally wall clock are placed kind of high on the wall, which would make it kind of hard to actually write on it. But whatever it is an awesome clock, you can get it from the MoMA store for $135. And I'm sure they have a super cute and modern step stool available so that you can reach your brand new wall clock.
"Designer Ricardo Saint-Clair seeks to foster communication with his interactive designs. This clever wall clock features a face made from a dry erase board, creating the ideal space to note appointments, jot notes, or leave messages for others. Comes with one dry erase marker with eraser, which discretely hides in the side of the clock. Made of sturdy plywood and laminate. Requires one AA battery (not included). Simple assembly required."Via
