@Acidburn - Thanks for keeping the demo up for the indefinite period. I do hope Zs prove themselves with more time. Zorro is great software. I wish I had it 10 years ago when I was first programming Larry Williams' stuff (not that the Oops! pattern is relevant any more.)

Of course I want to create my own stuff and not rely on the Zs. It's a great creative outlet. But with only a few spare hours each day, there is only so much time I can put into this.
