Software originally developed for the One Laptop per Child project can now be used on any old PC. Sugar on a stick, as it is known, can be run from a USB drive to give aging PCs a new interface and access to collaborative educational software. The software, designed for use by children, was launched at the LinuxTag conference in Berlin. It has been developed by Sugar Labs, a breakaway organisation from OLPC. “[Sugar on a stick] is a great new opportunity to breathe new life into these old machines,” Walter Bender, founder of Sugar Labs, told BBC News.
