Multifl0w is a tweak available in Cydia with the help of which it displays the applications open in the background by using the multitasking in iOS or the one implemented with Backgrounder. Multifl0w displays all open applications in the background in a manner similar to the one in Safari, moreover it also displays a preview for each open application. You can also see from the video clip above how intuitive the entire interface is and how easy it is to switch from one application to another. This tweak works on the basis of the plugin called activator, so it will consume resources constantly.
Multifl0w is available in Cydia for $4.99.
