can someone stupify an explination of a closed loop?

In aquariums closed loop refers to a system of water circulation involving an external pump. Water from an overflow drains down to a pump which delivers it back to the display tank though one or more outlets. Unlike sumps, which filter and process water before returning it to the display tank, closed loops are strickly for the sake of circulation and are usually used in conjuction with sumps in larger systems.

Ok I'll go with explanation #3 
A closed loop is one to where all the water stays within a "loop" of piping, and doesn't have a chance to "wander" (in the case as sump/overflow does). Typically you'd have an external pump connected directly to the tank via piping, that pump sucks water straight from the tank, and the output is PVC back into the tank, either through a manifold along the top, or sometimes directly through nozzles in the back/side/under the tank maybe with some sort of water switching device (OceanMotion, etc)

I think I can make it even simplier.
Closed loop = water circulates within the aquarium in a "closed" loop. Meaning it just loops around the aquarium as opposed to moving to sumps, other tanks, and so forth.
Most of the time people drill 3-6 holes in the back of the tank for a returns. A pump in fed the water from the aquarium and just squirts it out those varous returns. It generally serves only one purpose... circulation.

By the time I set up the closed loop with the Eheim 1262 pump, the OM 4-way, the bulkheads, ball valves, lock line and other fittings, i could have set up a vortec with a battery backup, and not have to worry how I'm going to clean the pump now it's against the wall...

correct. Since I have a standard glass tank I have zero holes drilled in the back of my tank. I do however, have two closed loop intakes along with over 16 locline returns.
If you take a look at page six of my 120 build thread there are more pics of a CL system. Everything you see behind and in the tank is CL related.
for a 62 gallon like yours, just buy a vortec. Easier to use, and you can get a battery backup for the pump.
You could use a SQWD for $30 or so and get variable flow. But they take quite a bit of flow away from the pump.
Rich is correct. the grey cylinder is the Ocean's Motions Super Squirt. there's a motor on top that spins a drum inside the unit. Two pipes are on at a time, and two are off. I have it set so the opposite corners are on at the same time. And I hate the noise from the motor. It's by far the loudest thing on my tank. My tank is in my living room and I will pull the plug on the OM if i'm watching a movie.
