I believe this needs to be updated for the Leap Motion SDK 0.7.7 because I can't find the files needed from the SDK. The only files I could find in the SDK were LeapPython.so, libLeap.so, and libLeapJava.so. As a result, when I run Fruit_Ninja.pde, I don't see anything displayed on-screen, and the cursor is changed to a crosshair until I close the program.

currently running processing 2.0b7, just wondering what you developed this in. i'm having some issues running it.

Hey all

After many tries, I can't get this app to launch. It runs and then promptly crashes, giving me the error:

Native code library failed to load.
java.lang.UnsatisfiedLinkError: no LeapJava in java.library.path

I've tried and retried adding the file, but nothing seems to work.

Any ideas?

"Cannot find a class or type named "HandArray""
Where is it?
