The :CueCat was a cat-shaped handheld barcode scanner given away free in 2000 by Digital Convergence. You scanned a code printed in a magazine or on a package and your PC opened the matching web page. Millions were mailed out, almost nobody used one twice, hobbyists reverse-engineered it within weeks, and it survives as the standing exhibit of dot-com-bubble optimism.
