Hate to be that guy... But out of I don't know 20 tries it only worked once. Maybe it's because of the room doesn't have enough light..

Hi rbn, possibly it's a light. Would you please do us a favor and send us a video of your lighting - that would help us improve? Also, please make sure that your palm is at least 1 feet away so as to completely visible by webcam.
