Bringing it to gaming, however—and eventually creating a gaming-specific tool—wasn’t so much an accident as a result of a doting father. “I’ve got four kids, three boys, and they’re Minecrafters.” Once one of his sons understood the tool’s function, he was desperate to have one. The reason? “So I can take my Minecraft experience to my friends, so I can take it with me.” It was this practical thing, says Mac Conuladh, of playing it from a drive and then being able to plug it into any computer that made him sure there . They did a pilot program and found that kids were using it to play games on multiple computers with different operating systems—exactly the kind of thing that the technology excels at.
