        Exercise: 
        Step 1. Write code that uses two creative prop assets.
        Then run an expression to alternate each tile. If I had a red and blue tile, it would go
        red, blue, red, blue, etc

        Step 2. Create a new multidimensional array by spawning wall props. Make it a 7x7 array
        The Wall props should stack perfectly without spacing and make a giant wall
