Mutable Instruments (who make really cool DIY synth kits) have some open source bread-board helper PCB's on their site.

Those are indeed very cool and useful.
+1! Really handy! I'm about to get a new big project on breadboard, and I was thinking of designing something like these in Eagle. I guess I'll use these!
Thanks!
