Developed in Hungary, the possibilities for this material are endless. Immediately I thought of office walls built with the material, to create separation, but allow light to flow from office to office. From an artistic standpoint, it lends it self to an interesting and unique canvas. And perhaps some interesting inter-office communication.

What will they think of next?
