Benham's Disk

Hey! I need help with my project (Benaham's Disk). All I need is some websites that can supply information for my project (some info on Benham himself would be nice too.) You can email any information to JuliaID@hotmail.com or AMSCheerleader@hotmail.com (it will probably be easier to answer on the first one.)

Thank you,                                                                                                                        Julia Incerpi Diaz
