Redstone ideas...

Heads
General, When a player Shift clicks or presses while touching a head, it will change mode. When given a Redstone update the head will act accordingly to its mode. Each sound an animal can make will have its own mode, each animal head would have a dispenser and dropper mode where it could be used as a dispenser or dropper, and animals could have special modes based on their "personalities", or features.

Special Head abilities proposals
Llama: Spit ability

Ender Dragon: Fires Dragons Breath

Guardian and Elder Guardian: Spikes come out of head, knockbacking nearby mobs

Creeper: Hiss Dispenser modes- Hisses before or while dispensing item

Wolf: Eyes turn red

Enderman: Opens mouth to scare mobs away

Mob interaction

 * Shulker: When a Shulker receives a Redstone signal it will stay open as long as that signal is provided, after being provided with a signal the Shulker will only open with this signal.

New Blocks

 * Redstone Jack O' lantern: Jack O' lantern but red glow, gives Redstone signal in the way facing or backwards when entity passes directly in front of it.
 * Redstone command block: Changes Redstone related rules such as Redstone tick time and disable certain Redstone circuit blocks from working, or affect Redstone in a certain area

Example: 3 redstone lamps and a lever are surrounding a randomizer, if the lever is activated, just 1 lamp will activate. each time the lever is pulled, onle of the 3 lamps will glow up, with no order of activation, similar to how the dispenser fires arrows from random slots.
 * Redstone Pulse Extender: Alterable, change it to say how long of a signal. Looks somewhat like a Redstone Repeater because it moves a Redstone torch along itself, but it has 3 Redstone torches on it.
 * Nether Redstone ore block: is a variant of the regular redstone ore block. Its found normally directly below lava seas. It drops 1-3 exp orbs and 4-5 redstone.
 * Redstone Randomizer: crafted with a redstone block at the center, copper ingots in the edges and a button at the left slot. This will provide redstone signal to random nearby redstone connections, it can only interact with 3 adyancent blocks, since a energy producer is needed.

Redstone Related Mobs

 * Redstone Golem

Like Iron Golem but made with Redstone and Redstone Jack O' lantern and gives off Redstone signal in a small radius
