Yes we are probably talking past each other here a little, but I enjoy and respect your work on SuperGlue. Not having used Self I don't understand the distinction between it and Morphic.

There clearly is a distinction between textual and visual, but at the same time they support one another: text is made out of pictures, pictures can be described with text (e.g. svg). For me the aim of visual programming language research shouldn't be to disparage or get away from the composition of symbols, but to supplement that with mental imagery. As I see it, mental imagery and language are most valuable in combination.

I'll look into sketchpad and toontalk properly though, "truly" visual language is a fascinating area.

Self is a language, Morphic is a GUI toolkit/framework/library. You can play with Morphic implementation in some Smalltalks (I did it in Pharo) and even in JavaScript: http://www.chirp.scratchr.org/blog/?p=34
