Illusions
Ray Hyman believes that he was responsible for getting Andrus interested in optical illusions. Hyman showed him the Mach-Eden illusion using an index card. Andrus didn't seem interested, but came back to Hyman some time later and showed him how he had improved it by inventing an illusion of a house.
Speaking at the Skeptic's Toolbox about the importance of understanding optical illusions, Andrus said, "The point of demonstrating illusions is not merely to show we can be fooled... rather to appreciate that the human mind is in fact working correctly... we look at a parked car on the street, we assume that the part of the car we can't see is there too; our brains have to do this so that we can make sense of the world around us".
In 1954, Andrus created the famous "Linking Pins", a close-up illusion in which closed safety pins are rapidly linked together in twos, threes and chains.
Invited by long-time friend and fellow magician Ray Hyman, Andrus brought many of his optical illusions to the annual Skeptic's Toolbox, held each August on the University of Oregon's campus. Two of the more popular Andrus illusions the "impossible box" and "Oregon vortex plank illusion" are explained in this Skeptical Inquirer article.
In the months before his death, Andrus continued to invent illusions. His media were common household items: metal springs, rope, wire, cardboard, wood 2 X 4's and steel rods. Many of his illusions are viewable on the Internet and some have already expanded on his inventions.

Famous quotes containing the word illusions:
“The time comes when each one of us has to give up as illusions the expectations which, in his youth, he pinned upon his fellow- men, and when he may learn how much difficulty and pain has been added to his life by their ill-will.”
—Sigmund Freud (1856–1939)
“Exploitation and oppression is not a matter of race. It is the system, the apparatus of world-wide brigandage called imperialism, which made the Powers behave the way they did. I have no illusions on this score, nor do I believe that any Asian nation or African nation, in the same state of dominance, and with the same system of colonial profit-amassing and plunder, would have behaved otherwise.”
—Han Suyin (b. 1917)
“When Wilson got upon his legs in those days he seems to have gone into a sort of trance, with all the peculiar illusions and delusions that belong to a pedagogue gone mashugga. He heard words giving three cheers; he saw them race across a blackboard like Mexicans pursued by the Polizei; he felt them rush up and kiss him.”
—H.L. (Henry Lewis)
