Sorry man, I personally don't recognize it as being a common/tested/known frame. I could be wrong though. Either way, I really like the looks of it, especially the top tube.
Anyone else? I'm interested. It reminds of a specific name brand frame that I can't quite place. I was thinking it looked like a Cube frame at first, but that wasn't it. Maybe it's a chiner frame that I just can't think of.
