All I can say after watching the video is HOLY FREAKING WOW MAN! I can't help but to say that when it comes to machines you just basically replaced them all. And not with just single block power gods but immersive multiblock structures to make machines out of. This is truly a creative yet simplistic approach to mod pack machinery.

I personally was inspired by what I seen as being possible with this mod, and hope to pass that inspiration on to you to decide if you feel that ModularMachinery would be enhanced by my ideas.

One would be a way to interface with Open Computers. I do understand that "MM" was just released and you probably have more pressing kinks to work out before adding something like this to it.

Another would idea would be to implement functionality with another mod, Resource Loader, so that other textures could be applied once a machine has been correctly formed. Granted I doubt it would be more than modifying the textures of a completed machines exposed faces. Kinda like Immersive Engineering but instead of changing how the machine renders it provides a more fitting texture.

That's not to say there is anything wrong with the provided textures, but you have unleashed the ability to pack makers to provide custom multi-block machines. I'm sure that ability to provide an aesthetic appearance that fits the packs theme would just be mind-blowingly good.

I was just about to comment these suggestions as well. Great mod, thanks for all your hard work!
