This PlayStation controller may look strange, but it's actually a sex toy. Wait, no, it's a high-performance racing controller. The two controller halves meet at a swivel in the center, which controls turning, with the shoulder buttons acting as accelerator and brake. Sadly, because of its weird appearance and the lack of support in Gran Turismo 3 and 4, the controller never really caught on.
