Earlier I blogged about ObjectDock and their Flyout Menus, but there is another application which is really better and good 
It is RocketDock . Its sure better than ObjectDock in terms of Performance and memory usage. And there is lot more to enjoy RocketDock! The Mac Leopard Fan and Grid menu!
Here are some screenshots,
