This fits a niche between Scratch and Squeak Smalltalk. Scratch is a very neat visual development environment aimed at learners. When you hit the limits of what Scratch can do, there is no easy path into Squeak. Squeak is also neat and powerful, but can be a bit overwhelming. This gives you the simple visual programming paradigm of Scratch for programming in Squeak itself.
The interface is very fast and crisp; I look forward to seeing it progress.
