The 7Ps - Proper Planning and Preparation Prevents Piss Poor Performance
I think about that phrase a lot when I'm putting together circuits. Sometimes it works, sometimes I get carried away with the fun of building. However, (un)fortunately, I'm not onsite with the table so the best I can do is plan ahead and with that in mind I put together the rats nest below as attempt to plan out all of the inter-connectivity that we'll have on the table.
It was modelled in Fritzing *GASP!*. I know, but despite fritzings uselessness for pcbs and schematics, it does print a pretty picture and it had 90% of the device images that matched what we're actually doing on the table.
Hopefully design and reality can meet somewhere in the middle;
