Storyboard 1 - 3D Modeling 
This design is motivated by the belief that if Jack sees how the tattoo would look on their body, his expectation would be adjusted in a more realistic direction.
When Jack point his browser to RocketScienceInk page, he is presented with an interface consisting of a display area, and a selection of pre-designed tattoo organized by style. He also see some additional components that he can pick too, but he does not know what they can do yet. Since there are not much text, Jack tries to click at one of the style tiles on the bottom, which pops up a window:
Jack saw some design that he likes, so he tried dragging it on to the drawing area, which seems to be the most sensible thing he could do, and the interface display him with a preview of how that tattoo would look on his body. Jacks play around with it a bit, trying different things including the tattoo aging slide bar. Finally, he has a pretty good idea of what he wants, so he prints out the design, and the screen shot of how it looks on the body, and bring them to his favorite tattoo parlor.
Design Analysis
Learnability
This interface is rather simple, with everything done mostly graphically. The display area corresponds directly to the real world object (our body). So depending on some subtle details on how this is implemented, this interface have a potential for a very high learnability.
One main challenge that this interface would see is how to implement the control of the display area, since there are a few modes that the user can do: move the camera, and move the tattoo and their components. Because there are many things that the user can do, if the interface don't utilize different gesture well, there might be an excessive amount of instruction text, or buttons that can confuse the users.
Efficiency
Assuming that the interface respond within the perception fusion
