1.4.7 version of Minecraft holds some pretty iconic mods/packs many of which were in their first iterations around this time like Greg tech 1 and applied enrgistics 1 early ic2 and early Railcraft/Buildcraft, factorization and earl Thermal Expansion etc just to highlight a few iconic mods.

This version of Minecraft severely needs aesthetic mods because this avenue of Minecraft was slower to take off initially and we just left mods like super slopes behind. I know this version of mc was short lived but it has some great mods and carpenters blocks would be fantastic in this era of modded Minecraft.

Someone has back ported chisel mod to 1.4.7 all we need now is Carpenters blocks because its a great mod and we need slopes!!!! in 1.4.7!!!!
