I don't think the floor will be painted (Ron?)```

I cannot tell you the exact height.  It will probably be about 1.5 meters tall.```

This is a good question.  Other teams have asked about the pen.  The idea is
to have the pen be about as tall as the walls, maybe a 1 to 1.5 meters
square.  The two openings will be on different sides, and the doors will be
colored to differentiate them (red and blue, as the rules state).  I'm not
saying whether the doors will be on adjacent or opposite sides.  The doors
will be about 50 cm tall, and light enough to push easily.```
```Another possibility is to have the openings be open, with a small (2-3 cm) lip
on the bottom to prevent objects from rolling out.  Then, the outside of the
opening will be colored.  TO ALL COMPETITORS: PLEASE VOTE ON YOUR PREFERENCE!```
```> Have you decided if the arena will be hexagonal or square yet?
Most likely hexagonal, but still not completely determined (depends on how
difficult it is to fabricate).```
