Yeah!
I am definitely sure I saw that shape before! I bet that if you show us a wireframe, it will have 6 faces, two of which at the top and bottom, other two left and right, and last two in front and back! I definitely saw that being sold somewhere.
But I am definitely not clean myself... Not only do I buy models, I buy those tutorials too... Those Corona tutorials are just bought stock tutorials, and then I just put my content in them and claim them my own. If someone asked me for low-pixel version of the tutorials, I'd be totally screwed. :D
