 The virtual CAT Interpreter is a component of the [virtual Cross Array Task (CAT) platform](https://github.com/GiorgiaAuroraAdorni/virtual-CAT-app). 
 It plays a crucial role in translating student actions, which include gesture interactions and arranged visual programming blocks, into executable machine-readable instructions.
