They call it Sugar on a stick. It’s the collaborative open source software originally developed for One Laptop Per Child (OLPC), the hoped-for $100 XO laptop, which actually comes in a $199.

It can be run from a USB drive, giving older PCs a new interface and access to collaborative educational software.
