The idea of displaying the ball count on the "big screen" is for show reasons.
Of course it's easier to display it on the RCX or NXT, but it's not easy to read
for a crowd of childrens :-)
I also thought of using seven-segments LED digits which are very bright, but I
would have to make the printed circuit board and I don't have time for it.

It's a possibility, but I don't think we will have a NXT unit available for this
purpose. Also, I don't have it so I don't know how to do this, and it requires a
computer equipped with a Bluetooth module, which may be not available.
I'm using a Velleman K8055 USB Experiment Interface Board
http://www.vellemanusa.com/us/enu/product/view/?id=500349 which is very cheap,
it can be connected to almost every computer built in the last 8 years, and
comes with a simple DLL to use it.

A bit too much for our taste :-)
