Q:

Designing a Yahoo Pipes inspired interface

I really like the interface for Yahoo Pipes (http://pipes.yahoo.com/pipes/) 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? 
I especially like how the pipes behave and how they are not just straight lines.
Edit: The application would be web-based. I'm open to using Flash or Javascript. 

A:

WireIt is an open-source javascript library to create web wirable interfaces like Yahoo! Pipes for dataflow applications, visual programming languages or graphical modeling. Wireit uses the YUI library (2.6.0) for DOM and events manipulation, and excanvas for IE support of the canvas tag. It currently supports Firefox 1.5+, Safari 2.0+, IE 7.0, Opera 9+ and Chrome 0.2.x.

A:

Try JSplumb.
The main structure is HTML/CSS, the connections can be SVG/Canvas/VML*
Great documentation very clean API and live demos 
*Configurable or is automatically set by detecting browser's capabilities
