At first, the goal was not to design a VPL, it just evolved this way. The idea was to make it simple to do image and signal processing. Currently, most "features" you would expect from a language are there: conditions, loops, functions/arguments. The features it has now are features that are/were useful to us (the GUI was the last part being written). The main thing to know about it is that it works by "pulling" on data, and not the other way. We currently have "toolboxes" for the following things: speech/signal processing (both real-time and batch), image processing, neural networks and vector quantization.
