Today, I've spent some time on ColorHug software (which I've preordered some time ago).
The first missing bit there were Debian packages. There are already some packages available for Ubuntu, but I've chosen clean start and did all the packaging on my own. The packages are now waiting in NEW queue (which is amazingly empty in last months) and will hopefully get accepted soon. In case you are too impatient, you can look to git repository on Alioth (you will need libgusb as well). Packaging effort lead to writing (quite minimalistic) man page for colorhug-ccmx, which I've also sent upstream.
The other thing, where I can help right now (not owning the device itself) is translation. As you can see on Transifex, my task is done here and Czech translation is complete :-).
