Building my own Yahoo Pipes (taoofmac.com)

Pipes was the only example of the "no/low code" idea that ever made me believe that possible future was remotely feasible. I saw a fair few co-workers produce some really interesting things with Pipes, and many wouldn't have known where to begin if you sat them down in front of a Python prompt with lxml. Seeing them chain filters, mangle date formats and input types was really cool.

The screenshots in the linked article make me hope that similar tooling can rise again.
