These planters, collectively named the Kuiper Belt after a region of our solar system beyond Neptune, are meant to represent "life forms which haven't yet been discovered." Life forms like...the circle! And...two circles on top of each other! In any case, though, these are way more interesting than the average planter, they might just lead to learn something about space, and you probably wouldn't have to worry about always hitting your head on a potted plant depending on where you hung them.
