Getting felt up on a train isn’t so great, right? Well, depends on the circumstances, but for the sake of conversation, let’s say you weren’t asking for it. Game developer Takahashi released an app two years ago for your mobile called Anti-Groping Appli which has been gaining popularity. The program flashes progressively threatening messages on your mobile to touchy-feely horn-dogs on crowded Japanese trains, starting at “Did you just grope me?” working its way up to “Shall we head to the police?” with each key press. It’s a free download, but searching for sites in Japanese is a bit outside of this blogger’s scope. Leefe has managed to dig up a download link, but it doesn’t look to be compatible with BlackBerrys. If you’re packing anything else, give it a shot!
