Our fridge is covered in Post-it Notes, phone messages, reminders to one another, and random messages. Beyond the obvious waste of paper, the clutter is an irritant every time we walk in the kitchen. Which is why we just ordered a Lumi Pad.
Magnets mount this to the fridge, and special markers write with light. Switch it on, and see your text displayed. Don't want to leave it on all the time? This clever gadget has a built in sensor that reacts to movement - if someone walks by, your message starts flashing to them. The 5" fridge magnet version of Lumi Pad is £ 19.99; we haven't found an American store that sells this version, but there is a 7" version of Lumi Pad on Amazon.com.
