Once you have all your prerequisites installed, you'll want to make sure that your Leap Motion Controller is properly connected. If you've installed the Leap Motion Gemini software and have your Leap Motion connected to your PC, you should see the following icon in the Windows 10 Icon Tray.
If the Icon is Black it means that the Leap Motion is disconnected. If it's yellow or red it means that there is something wrong with the connection.
You can test further by opening the Leap Motion Visualizer. Right Click the Leap Motion Icon, and select Visualizer.
You should be able to see your hands! Woah! Cool!
Make sure the visualizer is set to "desktop mode" and you're all set! Let's play with some blobs!!!
