Add a Computer (PC) Block to Minecraft

Minecraft could have a craftable “Computer” block that acts as an advanced redstone controller.
Crafting recipe:
[ Ghast Tear ] [ Copper Ingot ] [ Ghast Tear ]
[ Glass      ] [ Redstone Dust ] [ Glass      ]
[ Iron Ingot ] [ Iron Ingot    ] [ Iron Ingot ]
This recipe represents a powered device (ghast tears), conductivity (copper), a display (glass), and logic (redstone), all built on a strong iron base.
Features:

Opens a simple GUI when used

Can control redstone signals (like timers, switches, or logic gates)

Allows players to create more advanced contraptions without replacing classic redstone
Why this is good:

Expands redstone possibilities

Encourages creativity and engineering

Balanced as a late-game item (requires ghast tears)
