Samek created quantum leaps [1], an open source implementation of HSMs designed for use in embedded or realtime applications. If you've ever designed something that should respond to requests/activity, you probably understand the challenge of representing and understanding the multiple concurrent states your software system inhabits. HSMs (aka statecharts or Harel statecharts) are a great way to model this problem domain. [1] http://www.state-machine.com/ http://www.state-machine.com/
