Spde is an offshoot of the Processing environment to support sketches written in Scala, a powerfully object-oriented and functional language.

In contrast to the PDE, Spde is a deconstructed toolkit. For starters that means you bring your own editor and Spde will compile and run a sketch whenever you save it — that’s one option. The entire process is controlled by Scala code you can use or override. This structure should make Spde easy to extend and customize. But who knows, for now it is just a scrappy little thing with big ideas.
