I wasn't satishfied with existing applications for binding joystick to keyboard inputs. I couldn't find a single tool that could mimic analog controls by PWMing/pulsing keystrokes, so I made my own, so I could finally have proper support for my joystick in games that didn't support it (Mainly GTA online for helicopter ownage)<p>Its mostly useful for stuff like that, making bad PC ports work with joysticks, but I guess you could use it for accesibility as well as it also can bind mouse to joystick etc.<p>I also attempted to make a HTML5 player for an old physics sandbox game called Phun / algodoo. It kinda worked, but I put it on hold because I got annoyed by some problems I had with the physics engine I used (LiquidFun)
