TOBIAS WONG, designer and conceptual artist, died (b: 1974); A designer whose outrageous send-ups of luxury goods and witty expropriations of work by other designers blurred the line between conceptual art and design. A provocateur, Wong operated on the fringes of the traditional design world, creating objects like a stack of 100 $1 bills, bound in peelable glue like a notepad; a gold-plated McDonald’s coffee stirrer, a riff on the plastic version that was popular among drug users before being withdrawn); and a diamond mounted up-side down, so that the wearer could use it to scratch graffiti. His death was ruled a suicide.
