In Angewandte Chem. early view, there is a nice little paper reporting the first ionic liquid that is both magnetic and fluorescent. So one could have a drop of it in tube, with another, immiscible liquid, and move it around with magnetic field, and watch it glow. And once that becomes boring, I am almost sure there is a brilliant application for this just waiting to be discovered. Just need to find my thinking hat and put it on ...
Hm, how about some new display technology. A new kind of lava lamp. Or for spooky floating aquarium lighting? Still looking for that hat!
