@pattyland With the commit, it runs splendidly. I find that the swipe detection is sometimes a bit sensitive when moving the hand into or out of frame, but overall a very pleasant and fluid experience. Cool indeed!
As for Touchless, you don't need to worry about interference, as it is disabled when the active browser window is running a Leap Motion web app. If you fire up Touchless and run the plugin, you should find that it isn't active while you're there (provided that you have Enable Web Apps checked).
Scrolling would be a great addition to the plugin. I'd also love to see a "random post" gesture
