Some bright young thing
has created an Xbox 360 controller for a one-handed person.
His blog tells us he built this by request for a serviceman injured in Iraq. It's a left-handed version which works by setting it on your knee. Thus, tilting the controller against your leg acts as the right analog stick, which was the trickiest part of the controller to replicate.
The possibilities are endless... When is Soulcalibur released again?
