In this 1.7.2 / 1.7.10 Youtuber Blocks Mod Showcase:
This Minecraft Mod adds in Youtubers blocks that you can craft. Each one features the head of a popular Youtuber that will give you a special effect when right clicked or stepped on. But beware, not all of them are good! There also was a weapon, tool, and armor set added in the update.
