Work in progress
This is still in alpha stage, not fully playable yet, it's a technical proof of concept. Stay tuned!
So this (will be) the place to play. You'll need Firefox 1.5 (or any SVG enabled browser...) for it to work.
You can also play with the SVG file only (the standalone SVG demo at ufoot.org is no longer hosted), to get rid of pointless HTML.
Enjoy!
