Remember, the examiners will be marking the performance itself. Any special lighting or SFX will not assist your mark, it can actually harm your mark especially if the LX/SFX are not justified. A friend of mine is using a power point presentation (which is at the piss your pants funny stage) however, HE INTERACTS with the presentation. If it doesn't do anythin for you, doesn't progress the piece...or, is too complicated and you're trying to show off any technical skills you embody...the markers will pick up on it and it would be to your disadvantage...
Originally, I had a lighting design/plot for my IP, cause I'm actually a techie (I do Sound, Lighting and Stage Management gigs outside of school)...I showed my teacher and it was totally rejected, with my performance, its lights up...lights down.
In short, I agree with Wilmo.
