The start of a little game I was playing around with.  At the moment, up to 10 people can connect, and you can play with the little balls with the WASD keys and move them.

No chatting.
No collisions.
No error checking to see if you lose your ball off the screen.
No point to this really, except to have fun and experiment with sending/receiving data for a game, which I'll end up finishing when (if) I get more free time later...

The host is the red ball.  You guys can be one of the others.  The more people who log in, the more balls we can move at once!  LOL!

In all honestly, this is nothing more than a lag test to see how much lag might be generated as more than one player connects to the "game" and information has to be sent out to multiple parties, keeping them all in sync.  Feel free to stop by and wiggle your own personal balls on my screen for a while.  The more the merrier.  LOL!!

Scratch that.  My balls are still broken.  Folks on Discord popped in to help test the program, and it seems to work good here, but not anywhere else.  Debugging ensues, and the ball court is down for maintenance, at the moment.

While Steve scratches his balls, I'm working on some other text highlighting routines. Stay tuned.
