## What it is
Magic-Sand is a C++ openFrameworks application that operates an augmented reality sandbox by pairing a Kinect depth sensor with a projector. It projects color-coded terrain onto sand in real time based on the sand's height, with calibration tools and a simple interface aimed at home and family use.

## Use cases
- build an augmented reality sandbox at home
- project topographic colors onto sand using a Kinect
- set up an interactive sandbox exhibit for kids
- calibrate a Kinect and projector for AR sandbox
- run sandbox-based games on an AR sandbox

## When to choose
- you have a Kinect sensor and projector and want a ready-made AR sandbox app
- you need cross-platform support (Windows/macOS/Linux) on modest hardware
- you want simple calibration and a family-friendly interface

## When to avoid
- you need a general-purpose AR/VR framework rather than a sandbox-specific app
- you don't have the required hardware (depth camera plus projector)
- you need modern depth sensors other than Kinect without custom work

## Facets
- artifact type: application
