I love when people without any talent tell someone who's deeply invested in a personal project that "you have too much free time." I saw someone leave a comment like that once on a video of a voice-activated entry system a guy designed and installed on his dorm room door. The guy responded, "I'm a graduate student at MIT. The last thing I have is free time."
Apparently, in America guys are only allowed to spend their free time binge-drinking, pwning n00bs in Call of Duty, and hooking up with girls who lack self-esteem.
Keep up the great work, ady.
