But that aspect of Self comes mostly from Morphic. Anyways, Self/Morphic were a huge inspiration on my own work. There are deeper distinctions between textual and visual; think a Van Goh painting vs. a book by Steven King. They say "a picture is worth a thousands words," but actually, the worths are not very comparable. Text is much better at expressing abstractions than visuals are, which is why most VPLs mixin some text (though their are pure VPLs like SketchPad and ToonTalk).

I skimmed your thesis a few months ago; lots of good work there! But I think we are a bit out of whack on our world views (arts vs. PL), which is why we might not be talking on the same page.

Thanks, I forgot about the DigitalLibrary link :p. If someone is just looking for related work, better to try http://lamp.epfl.ch/~mcdirmid/mcdirmid07dead.pdf (smaller download as it doesn't embed quicktime movies).

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
