title: Designing a Yahoo Pipes inspired interface
body: <p>I really like the interface for Yahoo Pipes (<a href="http://pipes.yahoo.com/pipes/" rel="noreferrer">http://pipes.yahoo.com/pipes/</a>) and would like to create a similar interface for a different problem. Are there any libraries that would allow me to create an interface with the same basic look and feel? </p>
  
  <p>I especially like how the pipes behave and how they are not just straight lines.</p>
  
  <p>Edit: The application would be web-based. I'm open to using Flash or Javascript. </p>
