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.
