This is my first "Hello World" design created with BlocksCAD, aka "Hello Snowflake".

BlocksCAD is a 3D design tool with a blocks-based programming interface, which is quite easy to use - you can create shapes, move and rotate them in the three-dimensional coordinate system, or recursively perform an action by using loops.
It'd be a wonderful 3D design tool for STEM students to have fun with 3D design and learn visual programming concepts, or for anyone who would like to get up and running with 3D design without having the learn the intricates of 3D design tools.
