There are plenty of other mods in this pack that do almost exactly what redpower does.
I'll dispute that with logic gates and wiring but despite that I'll go along with your generalisation...
In that case why play minecraft? Lego does almost exactly the same thing.
Oh, and while I remember, that main palace pic I showed was improved upon, but I never took a pic. I quick tip for aesthetic house builders: for lighting the floor you can hide a torch 2 blocks down and then put a cover over it at floor level, covers let light through them ;] It worked really well for me despite needing more for decent coverage, they were all hidden.
Come on guys and gals, there must be pictures floating out there of redpower incredibuilds, soothe us all as we watch Dire program a turtle and make 9x9's for infinity.
