Suggestion on multilayer overhead slides, Don't.

A slide is not 100% transparent, & each layer makes the overall slide a 
little darker. This 'dingyness' can  lessen the positive impact that you 
are trying to make. Also, it is easy to get the registration slightly 
off between layers, esp. if there are more then 2. You also spend time 
lining up the slide registrations which also draws attention away from 
what you are trying to say.

Here's an alternative:
use your favorite slide producing application ( I get exellent milage 
out of the old stand-bys, MacDraw and MacWrite) to draw the first stage 
of your slide that you want to present. Save it under another name. 
Continue drawing untill you have the next stage that you want to present 
(original + next layer), save this under a different name. Continue 
untill you have completed everything that you wish this slide to 
present. Print/plot each level. You now have the equivilent of a 
multiple layer slide without the "dingyness" of layering, or the 
fiddling arround of trying to match registration marks.  You get a 
smoother presentation with less chance of problems.

Hope this works.
