Fluxx cards are the same size as common UNO cards. And Uno has a machine that spits out cards... When I read "Fluxx Frenzy" I was intantly reminded of the time we tried to play fluxx out of the Uno machine. Worth trying at least once. http://www.amazon.co.uk/Mattel-41943-Uno-Extreme/dp/B0000205XH/ref=sr_1_1?ie=UTF8&s=kids&qid=1259773408&sr=1-1
