Balloon filled Rouse Matrix panels may be bent to form corners. Many different corner angles are possible but they are usually right angles (90 degrees). This "Ginger Bread House" made right angle corners for the walls and another for the roof as part of the All Star Revue balloon convention in the USA.

Here the corners were leaned in to form a pyramid canopy at the Eastern States Balloon Symposium in the USA. The bends in the sheet of balloon filled Rouse Matrix make the panels stronger. No hardware was reqiuired to reinforce the balloons in the canopy. They simply sat on top of the metal frame used to raise the canopy overhead.
