Sandbox was developed in 2008 by iShed, part of Watershed in Bristol. The inaugural Media Sandbox supported six companies from across the South West to develop early stage digital media ideas. Now in its fourth year, 19 companies have participated in Media and Theatre Sandboxes, creating games, apps, installations and software.

In 2011 REACT launched Heritage Sandbox which supported six projects exploring new experiences around heritage. Books&Print Sandbox supported eight collaborations, and Future Documentary Sandbox a further six. Objects is REACT's fourth sandbox.

"It is no exaggeration to say that in five months the Sandbox has delivered as much as some mainstream publishers have done in five years"
