Abstract: A diary display and storage device of three dimensions (preferably helical) onto which visual data can be appended or a series of data units actually forming the device (helix) itself. A helically shaped device forms a compact storage unit onto which additional helical frames or units can be easily appended. The complete helical assembly can be axially mounted on bearings such that on rotation of the helix about its central axis, each data unit will appear in a sequential order in the same line.
