Guan Baihua has reinvented the wheel, oddly. The 50-year-old retired Chinese military officer has patented a bicycle with odd-sided wheels. The bike took him 18 months to develop and features a front wheel that is a pentagon and a back wheel that is a triangle. "There are too many identical mass-manufactured things. More and more, people like weird and rarely seen stuff. Making this bike gives people an alternative," he said. A single-cube ice tray, a hammer featuring a self-lubricating handle, and a social networking site are rumored to be Gaun's next big projects.
