Attachable gamepad... for Nexus S?

So, I just found out that the iControlPad is a thing. I got all excited, hopes up, dreams shattered. The damn thing doesn't clamp onto my curvy sexy Nexus S (no doubt Galaxy owners will have similar issues).

Hence, I must put forward this question... are there any similar gamepads for the Nexus S? Or has anyone found a way to attach an iControlPad TO the Nexus S?

And yes, I realise it can be used detached - but that's a bit tricky when standing on a train.

Edit: It seems I'm not very good at reading, you can now purchase a "universal holder" along with the iControlPad that will hold pretty much any phone to it - albeit in a less attractive fashion.
