Hide apps behind an app

Through Cydia I once found a tweak that let you hide apps behind another app. It would load up a black screen with a loading symbol when you clicked on the app. Then you could tap areas on the screen in a set sequence and it would load your hidden apps. If you didn't tap your sequence correctly it would just load your app after a designated timeframe? Anyone know what the name of this tweak was? I can't find it any more.
