Custom Theme website?

[Droidiam]

Does anyone know a website that you can kinda make your own theme? Like notification bars, icons, etc. There was a website that I used to change my notification bar but I can not for the life of me find it.

Try UOT Kitchen it does the majority of things, just not app drawers

A WordPress Theme is a collection of files that work together to produce a graphical interface with an underlying unifying design for a weblog.

And that has to do with adding a custom theme on a cell phone... how?
