Guys, after searching the net i finally found it on IRC. And here it is, for all of you that were inpatient like me!
Installation instructions:
for example, if u have invision installed in c:\, extract it to the following folder:c:\invision\invision\themes\. Then load the i2t file included.
if it doesn't works you can manually select the files in the theme manager. I was just the guy who packaged this. The author is Aegonk. (and notify me to correct the error)
More themes will follow soon..
ENJOY!
