Technology isn't just about design and hardware; sometimes it's about psychology, politics, sociology, and economics. The website of Stanford design prof Michael Shanks is hosting a student project by William Choi and Antoine Sindhu, a fascinating online course about slot machines (http://shl.stanford.edu:3455/TenThings/302).

From the site: 'Much research has been devoted to studying gambling behavior from various points of view, including the psychological, social, economic, and political bases and implications of gambling ... [just the same,] focusing on slot machines reveals and inspires the study of many sociological issues that have come to express themselves specifically and notably on these machines. Here, we examine a number of these issues, attempting to link slot machines to them in an effort to better understand and explain them.'
