Let me urge a bit of a caution: If you were supposed to complete this assignment yourself, you better not submit the work of IamSam as your own because all the instructor / professor has to do is ask you a couple of questions about the techniques you used, and it will become glaringly obvious that you didn't do any of the work yourself. Where I teach, a situation like that gets the student an immediate zero on the assignment (assuming they haven't cheated in the past), and if they protest, a hearing in front of our board of academic integrity (which almost never finds in favor of the student). This really isn't a good path to go down because for marginal students it can result in failing the course, then the parents get involved, graduation can be delayed, yada, yada.
Also, I assume that once you learn all the techniques Sam is showing you, you will do something similar by yourself using other starting images, since I'm sure you realize that all the instructor has to do is put what you submit into TinEye or Google Image Match and they will likely turn up this thread.
Just a thought.
