"SequoiaView is a [freeware] disk browsing tool based on the principle of treemaps, with one unique feature added, namely Cushion Treemaps, invented by Jack van Wijk. The principle is simple: each time a rectangle is subdivided, ridges are added. The result is a pattern of hierarchical cushions that show the structure in the directories and files. The user can set the height of the ridges as well as using lower ridges for deeper nested levels, offering a choice between displaying global information (high level directories) or detailed info such as individual files. The user can also choose between the original cushions and the squarified cushions."
"Files and directories can be selected, inspected and opened, but can not be modified directly. Users can define different color schemes to facilitate identification of certain file types or load a ready-made color scheme from disk. Files can be filtered on name, size as well as creation, modification or last access date or any combination of these."
"SequoiaView was developed based on research done by the Visualization Section of the Faculty of Mathematics and Computer Science at the Technische Universiteit Eindhoven."
"Cyberspace. A consensual hallucination experienced daily by billions of legitimate operators, in every nation, by children being taught mathematical concepts...A graphical representation of data abstracted from the banks of every computer in the human system. Unthinkable complexity. Lines of light ranged in the non-space of the mind, clusters and constellations of data. Like city lights, receding..." --William Gibson, Neuromancer, 1984
