sandbox

1. Common term for the R&D department at many software and

computer companies (where hackers in commercial environments

are likely to be found). Half-derisive, but reflects the

truth that research is a form of creative play. Compare

{playpen}. (In the UK this would be "sandpit").

2. Synonym {link farm}.
