Game Art: SixFt12's "Virtual Running with Grand Theft Auto IV" (2010)
"If this were built professionally, I'm sure this would be done electronically instead of mechanically. Figuring out how to make it turn left and right was the most difficult problem because as the elliptical machine handles move forward and back, the distance changes constantly between your hand locations and the controller. Solution: bike brakes." (SixFt12)
