Little Blocks Mod 1.6.4

LittleBlocks is a mod that allows you to polish up your creativity and optimize your redstone systems. Indeed, the size of blocks placed in a little blocks is divided by eight compared to its original size, so you can place 512 blocks instead of one. Be careful though with the size of your creations because the resources (memory, gpu / cpu …) increases proportionally with it.
