LumiPad 'Fridge Magnet Blinks Your Messages Using Motion Sensor

Stick up this LumiPad refrigerator magnet, and its motion sensor will trigger your written message to start wildly flashing in your co-inhabitants' faces when they walk by.

It uses your choice of three included colored pens with special glowing ink, and when you turn on the LumiPad your missives light up like a neon sign. Available in a desktop model for around $50 and this refrigerator magnet for $40, they both use four AAA batteries, and even when they wear out, the text is still slightly visible.

This looks like a fun way to communicate, and would have been especially handy back in the days before cellphones took over the world.
