Refrigerator Locker Magnet

What are those plants that you could buy on magnets?

I used to see some kind of tiny plant in a little pot no bigger around than a quarter, attached to a magnet. They were supposed to live in virtually no sunlight and no watering. I think they got all the water they needed out of the air? I'm not sure. But I saw them sold for putting on your refrigerator or even in a school locker. Does anyone know what I'm talking about? What were they called? I looked for some last time I was at Fred Meyer (which is where I really remember seeing them) but they didn't have any.
I might have some of the details wrong, but I do remember it was a little sort of spiky plant (kind of reminds me of a teeny aloe plant) that was in a little pot on a magnet. This was also quite a few years ago. Maybe it was just a short-lived novelty thing.

Presuming no one knows what I'm talking about, does anyone know of a plant vaguely similar? As in, requires virtually no sunlight and less than a lot of water?

They are bromeliads, or "air plants" and are still around in stores.
