The beta version does exhibit some strange behavior sometimes, popping up error messages upon actions that were completed successfully in the same exact manner earlier (and later), for example.

But it's easy to work through the glitches and play around with your project. It's also easy to find another Pipe that interests you and tinker with its components to customize it for your own uses or use it to build a brand-new Pipe.

The site lists the Pipes that have been run the most times or cloned the most times. It also features an active Message Boards area.

Some people have called Pipes the future of programming. I don't know about that, but it's certainly easy and fun. Go on, give it a try.
