You could get one of those portable projectors and take it with you.  There
are two versions that have caught my eye.  The first is a 'portable'
projector that will fit in a small bag.  It wouldn't be too cumbersome to
drag around, especially if you are already carrying a laptop anyway.  It's a
small box and features an LED light source.  I'm not sure how it would do
for brightness or screen size, but the LED systems do tend to have more
vibrant color re-production.  If the room you were presenting in was fairly
dark you could probably get away with it.  Here is a vendor link:

The next type are the true pocket projectors.  These ones are about the size
of a larger cell phone.  They would be very easy to cart around; you could
probably cram it in your laptop bag.  The drawback would be light output.
 It probably couldn't project a very large image and the room would have to
be very dark for the images to be visible.  It's more meant for presenting
to small groups around a conference table rather than a lecture hall.
 Still, the portability is nice.  Again, a couple vendor link examples:

I haven't actually tried any of these, but the LED based ones will probably
have better color reproduction.  If you found one that worked well you could
take it with you so you would always know what to expect.
