Can Java Programming be used in Programmable Matter

Greetings group. I am extremely interested in the concept of programmable matter, or the idea that small particles can be programmed to behave in a certain way and to form unique solid shapes that serve a transient function. For instance, here is a video that I came across on YouTube that demonstrates the concept of programmable matter. Keep your eyes on the suitcase to understand what I am talking about:

So my question is, do you think this is a possibility or just some futuristic whimsy? Could Java for instance be used one day as the core language of programmable matter?

Your ideas and discussion are welcome!

Thanks,
Aymen.
