Description

Interaction with Leap Motion <https://www.leapmotion.com/product/desktop>, based on the Web Socket API <https://developer.leapmotion.com/documentation/javascript/supplements/Leap_JSON.html>.

Here is a simple example applicaton that prints all events:

main :: IO ()
main =
  runWithHandler def [setFocused True, setGestures True] $ event ->
    print (event :: Event Float)
