I don't want to say we'll never program complex systems graphically, but the odds aren't very good. There's a reason why we stick to writing stories instead of drawing pictures, and those reasons extend into the programming domain.

The idea of graphical programming has been around for a long time, but I really think it should start to be taken seriously. In the game industry they've been battling with some of the most complicated systems, both as far as software and overall production. They've been trying to empower content creators with the ability to easily embed logic in the content and make it easier for designers to work on gameplay without becoming programmers. The new Unreal tech is all about these graphical programming environments with several tools that look exactly like Quartz Composer. Work like DabbleDB and some of the things you've been doing with editable UIs and realtime environment manipulation have been really inspiring me in this area. This is the kind of stuff that I'm really interested in. You realize this is the key to a potential world of mainstream programming, where normal people are able to program.

Tens of thousands, even :-) I figure the program counter has to increment for each fetch, plus the code will contain numerous branch computations, add instructions (and subtracts, multiplies, divides, etc will all undoubtedly use additions somewhere deep in their bowels), plus register indexing and oyher stuff. Probably adds up to more than hundreds of thousands of adds per seconds, especially with my PBook's 1.5 GHz clock. Lots more :-) This effort reminds me of back in the 80s when one of our hardware teams implemented our first hardware assist for the frame buffer (till then, all pixels were computed and placed in the fb by the CPU). I immediately suggested using it to do simple "parallel" arithmetic (more like SIMD, since the graphics h/w cycled sequentially through the pixels rather than swell fooping it in true parallel fashion). One of the guys took me up on it and implemented a visual adder, with the frame buffer displaying inputs and outputs while they were being computed. Totally worthless, but fun, in that twisted geek fun way. “chugging away at thousands of operations a second.”

You can also do similar things with <a href="http://www.omnigroup.com/graffle" rel="nofollow">OmniGraffle</a>. One of the sample documents for that application is a half-adder built using AppleScript actions attached to shapes within a document. Very neat.
