Cube

No Debian or Ubuntu packages.
Well it appears the .deb I thought existed was that previous one and, from what I can tell, it's no longer up online.
However, a little bird tells me you can just extract and run cube anyway using the latest release:
http://sourceforge.net/project/showfiles.php?group_id=91993
Just remember to read the README which tells you which files to chmod +x so you can run it.
I have the deb if you have hosting space somewhere.... I cannot vouch for the "Debian quality" of the deb which I knw (righlty) concerns jdong... Works for me well however on hoary....
