OpenGL version of Oculus Room Tiny

[stolk]

I was pleased to see a minimal sample app in the SDK, in the form of Oculus Room Tiny.
Unfortunately, this sample is using D3D.

Where could I obtain a minimal DK2 app that is based on OpenGL?
I intend to use the SDK provided distortion rendering.

Thanks,

Bram
