Custom icon layout

So for those that don't know, there's a nifty app called iBlank that allows you to create blank icons for the purpose of rearranging your home screen with icons in any spaces, and blank spaces as well (similar to Android).

Here's my question. I know there's an alternative to this that doesn't use winterboard and doesn't require "blank" icons; it just lets you place icons wherever. I know this because I've used it before, but I can't remember the name of the app for the life of me. Anyone able to help?
