You could have downloaded Quantum Moves 1.0 for Mac from our application library for free. This free Mac app was originally produced by Science at Home. The application is categorized as Games.
From the developer:
Play Quantum Moves and contribute to cutting-edge physics research. Your task is to find clever ways of manipulating and moving atoms. The game was born out of the dilemmas and questions physics researchers confronted with when they took the challenge of building a quantum computer in the basement lab of Aarhus University.
