Hi Everyone,
I have seen it before, just not in Gamemode 4. So I searched for Command Block Creations, that have the functionality of a Vacuum Hopper, and I found this Video from Jragon: Vacuum Hoppers in 1 Command. Credit, where Credit is due, right?
My Module here is made of 20 Command Blocks + Hopper Clock, with the Dimensions: 6*2*2
The Module Itself
What I tinkered together here takes Inspiration from Jragon, but also from the Custom Crafter Base Module. You will need that Module (I used the 1.8 Version) for two Materials needed.
Crafting Recipes:

Recipe Compressed Iron

Recipe Singularity Gem

Recipe for the Vacuum Hopper
Then you need to throw an Eye of Ender onto the Hopper, which then Makes the Vacuum Hopper:

The Ender Eye needs to be sunk into the Hopper
The Idea is, you create a miniature Black Hole that has an attractive Force on every Item in a Radius of 5 Blocks. The Lore on the Items is a bit Silly, but hey..

The Vacuum Hopper, with some Particles
I made a 1-Click that can be found here: http://pastebin.com/ikcPVMmv
No Scoreboard objective is needed. The scoreboard players tag function does the job just fine. The Armor Stand gets the Custom Name: GM4_VacuumHopper
That´s about it, really. Play around with the Module and have fun. ;)
