swackett XView in Mac App Store
($2.99) - swackett X is a whole new way to look at the weather. It converts complex weather data to easily-understood, visual weather reports designed for people of every age. Its unique approach combines raw weather data (current conditions, radar, and detailed forecasts) with thoughtfully crafted people symbols (called “peeps”) who always appear appropriately dressed for the weather.
swackett X is enhanced for OS X Lion with multi-touch gestures, full-screen mode, and in-app purchasing.
