Expression Blend and SketchFlow is a visual tool for designing and prototyping applications. Expression Blend breaks down the barriers between design and development that have historically slowed the development process to maximize the opportunities for synergy between design and development.
Expression Blend enables you to iterate and deliver on your ideas faster, creating powerful and refined solutions for the web. SketchFlow will revolutionize your speed from concept to production by allowing you to add all the interactivity, animation and transitions without writing code.
