Reaktor does the some thing with DSP. I can pick up a sawtooth 
oscilator, a 2-poly LP filter, an ADSR envolope generator, hook them 
together, and I've got a synthesizer. Not impressed? How about I hook 
together a couple of 1-sample delay units, some (+) and (*) nodes, and 
implement my 2-pole filter from first principles?

Other "module synthesizers" let you connect pre-built filters and so 
forth together. Reaktor lets you design new ones from scratch, down to 
the level of individual DSP algorithms. (On the other hand, it stupidly 
lacks any kind of true subroutine capability, nor any looping constructs...)

And the compiler. And the processor implementation. And, hell, the 
entire hardware system you're going to run it on. And, if you want to be 
picky about it, assuming your trust mankind's understandig of the laws 
of physics...
