I have three questions. First, I'm going to be using a small, home projector for some projections during a show and after doing the math with where I'm going to hang it, it may not be a large enough projection. Is there any to "jerry-rig" a separate lens from a fresnel or S4 or from anything to make the image larger? Second, Is there any software thats designed for projections that can give more effects and freedom then PowerPoint or OpenOffice Impress? Third, What's the best way to stop the ambient light that comes out of a projector without a physical barrier? Is the a setting thats standard with most projectors? The projector that I will be using is a NEC NP40 (NEC NP40 DLP Projector). Any help or advice you can give will be greatly appreciated.
