For those who are wondering its a "language" with sole purpose to change one input for another.
As a result you can make your computer controlled with a kinect or wii mote, or speech.
Or let your computer react on your brainwaves using a think gear or whatever its called.
It can also give your computer multiple cursors and if you want it can "swallow" your keyboard and mouse so if you have multiple connected it can see the difference between the two.
As a result you can in theory have one normal keyboard and one where every key is a macro or something
Or what about using the internet as input
Sadly it is very, very out of date.
