What do you call this plant I've seen in a magazine?

In a gadget magazine today, I saw a small houseplant that was submerged in water in a see through box. It could have been any plant, it was more the vessel it was in that I am interested in. The brand name was bio-something and it was in essence just a sealed vase but it looked very arty and meant you don't have to water it as much. Does anyone know what it's called?
