It’s not clear exactly what game this floor is for, but you can easily imagine a maze or some other puzzle that needs to be solved with footsteps. Light-up floors are nothing new here ...

So now we know that light can come from different sources, and that some objects are transparent, some are opaque and cast a shadow, and some objects reflect light!

Smooth, shiny surfaces such as mirrors and polished metals reflect light well. Dull and dark surfaces such as dark fabrics do not reflect light well.
