This is a part I sumbitted to CM gerrit (Only the new widgets that don't use resources but a shape, marquee effect, plus 25% transparency resource and that awesome pressed effect), wich I hope Andrew neals merges soon. As for the widget, I just themed a few images with Gimp, overwrote layouts with holo_light, and some sources with holo_light too (too much work now that I think it :/)
This is a preview
Remind this only themes widget. If you want to theme the entire app, use black theme together with this.
All the credits go to CyanogenMod team, specifically to Andrew Neal, who wrote Apollo.
For installing, push to /system/app, replace if you already had it, and set permission to 644
EDIT: I'm sorry if it looks ugly or somehow messed, im not themer but developer, not used to do PNG's but .java & .xml (those are surelly not messed )
