Konfabulator is a great example of why it’s worth owning a Macintosh. This Swiss army knife-style software is a JavaScript runtime engine that allows for quick, easy development of beautiful ‘widgets,’ which can do everything from display the time or weather, to rotate your iPhoto pictures, to allow remote control of your iTunes library. The software takes advantage of Mac OS X’s powerful rendering engine to gorgeous effect — the widgets are edgeless and shadowed and often transparent.Below, just a few examples of Konfabulator widgets. Clockwise from top left: The Weather, Calendar, Analog Clock and iTunes Remote.
