Photograms are contact
prints made by exposing light-sensitive photographic paper to a light
source while objects cover part of the paper, then developing. Here's
a variation using heat instead of light.

Quick Look At:
It wasn't that long ago fax machines were a luxury. I saw one of the older technology ones in the 70's. Paper was placed in a spinning drum, while a scanning "eye" slowly worked its way across the drum from end to end, taking several minutes to do what now takes 30 seconds.
Now, of course, they are everywhere... required equipment for businesses and even many homes. Either standalone models or built into computers, they can be a quick way to reach next door or halfway around the world with a short phone call.
An alternative to penpals or epals (the internet equivalent), consider using faxes for classroom to classroom communication.
Another artsy project involves faxing artwork to another machine, deconstructing it by cutting it up and/or manipulating it with a photocopier, then faxing it back. The more generations of faxes, the more it breaks down. Sometimes sharp and clean isn't necessarily better.
