Whether or not it has ever occurred to you that a glass dome full of live jellyfish might be a nice thing to have in your living room, owning such a dome is now an option thanks to the Darwin Tank from Darwin Sect, currently trying to raise $35,517 through a Kickstarter. The tanks generate a light current to keep the jellyfish moving (otherwise they would get caught in the filters) and they do not come cheap: to get one, you have to donate around $1,500.
