The first spreadsheet that allows the display of images in a cell is ASP [19], but it contains no advanced capabilities. Levoy's ``Spreadsheets for Images'' system [15] and Hasler et. al.'s IISS system [10] examine ways to profitably extend the spreadsheet paradigm to images (as well as to other datasets--Levoy briefly mentions 3D volumes). For example, Levoy shows how a spreadsheet can be used to examine an image processing pipeline, and Hasler shows how many image processing tasks can be efficiently organized in a spreadsheet system. These two systems illustrate some of the capabilities made possible by extending the spreadsheet paradigm to other domains.
