16 Icon Homescreen Stock Zen
I'm more than sure there is another version of this out there but I will throw this out anyway. A few months ago someone requested the default zen with 16 icons on the home screen. I was happy to help out, then the other day I noticed it has been downloaded 55 times without me posting the link. I figure there may be a few that are looking for it so here it is.
