Minecraft beta 1.2 came out on the 13th, and among a host of fixes and new features were these three things: note blocks and cake.
Of course any mention of cake among gamers leads to Portal reference and comments about whether the cake is or is not a lie. I should have known that someone would take the note blocks it limit. After all this is Minecraft, the game where someone built an actual arithmetic logic unit. Watch the whole thing, you won’t want to miss the finale.
