Legal Tender (1996) was the first Internet telerobotic laboratory. Visitors to www.counterfeit.org were presented with a pair of US$100 bills, one real the other counterfeit. Users could perform experiments on the bills by registering with an email address. After receiving a password, the user was assigned a random sector on either bill A or B along with a magnified view of that sector:
Users were then invited to choose an experiment to perform on their sector.
After choosing an experiment, users were reminded of the following law and asked if they want to proceed.
Title 18, Section 333: Mutilation of National Bank Obligations:
``Whoever mutilates, cuts, defaces, disfigures, or perforates, or unites or cements together, or does any other thing to any bank bill ...shall be fined or imprisoned.''
After clicking "proceed", the results of the experiment were illustrated. Samples of the burn test are illustrated.
