Interface toolkits in ordinary application areas let average programmers rapidly develop software resembling other standard applications. In contrast, toolkits for novel and perhaps unfamiliar application areas enhance the creativity of these programmers. By removing low-level implementation burdens and supplying appropriate building blocks, toolkits give people a "language" to think about these new interfaces, which in turn allows them to concentrate on creative designs. This means that programmers can rapidly generate and test new ideas, replicate and refine ideas presented by others, and create demonstrations for others to try. From the Series:CSE Colloquia - 2007
