I have been collecting rubber bands from newspapers and produce for some time to use in making rubber band balls with kids. I just saw an ad for a book called Rubb-Origami that has some fun ideas on things to make out of rubber bands. You can also send your old rubber bands to them and have them make a new creation (for a fee).
The authors teach how to make little people and animals out of rubber bands. Info at; smattworks.com
