Also keeping an eye on this thread. I posted one a while back (here) and it didn't help me achieve any goals, although I got some cool ideas.[/QUOTE]

Found some good Ideas on your previous thread but more helpful were all the comments defining the problem. It's not that you can't arrange many bars in a small place, its that you need so much space around them to get the one you want free.
Once I realized that was the problem the solution for me came pretty quick. I already had two sets of sturdy 15" posts in the wall so I turned those into the dock for a removable storage rack that I can pull down easily and have all my bars accessible on my workbench.
I picked up a discarded trade show exhibit frame a few months back that had all the tubing and T clamps I needed for the project. It was one of those times when everything just comes together.

Here is what it looks like now. At first glance it's the same just organized.

But each rack slides off and then sits on a piece of tubing clamped in my vise.
