Blaz3, noname hd and Blue iPad v2 are a few that work.
Here is noname hd on my ipad. I have altered the code a bit in order to have larger, bold and red icon folder names. They are originally black with white shadow. To hard to read.
Also have infinidock and overflow active for the dock.

How do you go in and change the pics of individual icons? I tried the darkness theme and it only changed a handful. I know you have to ssh into your phones directory and resave the icon images but not sure exactly how to accomplish this.
You utilize iFile to change the code. Basically, find an image of an icon you like by downloading a tweak like alt icons" via iFile, copy the file of the image, then find the file within the theme you downloaded, paste in the new icon file and overwrite the old one.
It helps if you start learning how the code works and where items are stored. Most themers tend to use similar file folder naming and placement. Makes life easier. Learn the code on your own. It's not hard, just a lot of looking around on your own via iFile.
If you add weather data via a theme, you'll have to go into the weather folder and change that code too. People usually use yahoo weather, which is typically a code like usca1234 or 12796886. You get the code by surfing the net to yahoo weather and type in your city, then look at the address bar for a code that looks like that. Easy stuff, once you know what to look for.
