A couple days ago I started a new Google code project called: “Tractable”. Tractable will not only include an improved version of the “rotatable scalable” but supply users with a complete behavioral multi-touch framework. This project will be published under the MIT license. Here you’ll find some excerpt of our road-map:

Roadmap Tractable project
Introduction

Tractable is a new AS3 class for rotating scaling and dragging DisplayObjects in a multi-touch enabled setup. It’s a direct competitor with the build-in gesture “pinch” libraries from Adobe itself which it shipped with the latest release of the Flash Player 10.1. These libraries are insufficient when it comes to intuitive and “free” control allowing only one manipulation at the time (rotate vs. scale).

Tractable also forms an alternative to parts of commercial efforts like Ideums GestureWorks which allows it’s users a great deal of manipulation freedom. However, we will not create a full-blown framework like GestureWorks. The tractable project will only focus on the creation of efficient manipulation classes which can be reused in several environments.
