Does anyone know of something similar that lets me watch data "flow" through my code at a human readable pace? I dont use ctr-z, Its surprising to me that people code this way, but I do tend to spend a lot of time thinking about how my data would flow through my current code set. It would be great if I could easily and almost cartoonishly visualize it. Anything like that out there? gdb is just to abrubt an harsh to use.
