Natural Order- Ideations and sketches

My initial idea was to design a 'spiral' shaped tower. It is combined with three vessels which are in different heights, sizes. It allows the user to put different sizes and scales of documents all-in-one. Also, I thought this shape was ideal for the user who wants to throw in their stuffs to the basket without thinking too much of 'organizing'. Throw things into each slots! The other reason [I liked about this idea] was that it has a room to create its own 'sculptural beauty' when the user puts in each file/paper/memo with different colors, material and sizes.

However, while I was playing with paper and aluminum, I found more simpler solution than to put three pots vertically in a centric order. Magnetized sheet metal and plastic came into my mind as the material. Magnetic feature can hold three units in one easily. Also, it allow the user to assemble more than three with various ways of putting them together.
