Delta Drawing was intended for children age 4 to 14. It features a functional programming language for executing scripted drawing and painting instructions.[2] Spinnaker sought to improve on the educational value of Logo, an earlier educational programming language that could also program turtle graphics.[3]
Power Industries LP of Newton, Massachusetts later acquired Delta Drawing Learning Program and continued its development. They released the new version, Delta Drawing Today v4.0, in 1990,[4] and eventually a Spanish-language edition: Delta Drawing Today Version Español.
