Here's a student produced short clip from Gobelins. It was created as an exercise in special effects, but this little vignette displays far more than just completing an assignment. The students have included some camera movements that enhance the setting (at the beginning of the clip) and action at the end of the film. There's also good character posing and staging in the superhero's introduction and battle sequences. I also like how the students turned this assignment into a full scene complete with backgrounds, camera moves, and sound effects.
This clip reminds me of how important it is to experiment when you have the time--every technique that the students display in this vignette can be applied to future projects.
