LabVIEW is used at my dad's work (http://www.aei.com), it's a graphical representation language where basically UML and code are combined. You create circuits of sorts that represent functions, loops, etc.

It's mainly for hardware interfacing i believe...Although not much coding is used, the more you know about basic programming the more complex programs you can write, and quickly, at that.

It's neat, but very slow from what i remember.
