Picture of the day

Shown here is a three-dimensional rendering of a high-end espresso tamper with an integral bubble level, created using Cobalt, a computer-aided design computer program published by Ashlar-Vellum. The program can be used in either direct-modeling mode to create and edit objects, or the highly structured, history-driven parametric way. Cobalt's interface was designed in 1988 by Martin Newell (who created the Utah teapot in 1975 and went on to work at Xerox PARC, where the WIMP paradigm for graphical user interfaces was invented) and Dan Fitzpatrick.Image: Greg L
