Man, I expressed similar thoughts years ago.  Software pumps data 
in, operates on it, and pumps new data out: why don't we have 
proper visualization tools for those data flows?  Only being able 
to freeze program state and inspect it at repeated snapshots in 
time with a debugger is so backwards: it's like we're still stuck 
in the '80s.

Then, right after I see you mention it too, I happen to run 
across a recent lldb frontend for OSX/iOS- he gave up on Android 
;) - that does exactly that:
