Once you can start to visualize the voltage flow in your brain its so much fun to deal with the cables.
Some modular performers like Keith Fullerton Whitman have a very dynamic approach to patching. I've seen shows where he was aggressively re-patching throughout the performance and hot-swapping connections on the fly. I'm talking several patches in a minute. It wasn't subtle, either. It was a nice contrast to many performers who tend to design their system as a fixed structure and then play from there.
