Waterbear is a toolkit for creating drag-and-drop programming languages, with some example languages you can play around with and learn from. The goal is to make it easy to wrap other existing languages with Waterbear blocks to create draggable, snappable syntaxes for them.
I want to show that the notion of scalability is every bit as valid when applied to programming languages as it is when applied to programs or algorithms. I'll also discuss several well-known and not so well-known programming languages from this perspective and give some concrete recommendations, as well as discuss some of the social factors which hinder progress in this field.
