Personally I believe that the textures for the minetest blocks are not the best. For a long time I've actually wanted something like this but it's never existed untill now. Take the TA2 flywheal for example, looks too realistic, however with the texture pack it just gives it that nice pixilated crispness of minetest.
Well i was searching for mods a bit like the well known minecraft mod "create" i came across this mod. I was instantly enchanted and designed giant factorys in survival automating the entire game experience. The Official server for this mod is also equally as with a great active comunity and a kind staff team always wanting to help.
