Here is a small glowing model of a beacon from the game Minecraft. The light comes from a cheap LED headlamp. The LED, batteries, and switch are in the base (The part covered in black electrical tape; made from a sheet of aluminum). The LEDs glow through the inner cube, which is made from clear plastic colored blue, with hot glue inside to diffuse the light. There is a hole in the top, so that a beam of light can shine through like in the game. The inner cube is encapsulated inside a larger cube made of clear plastic. I made this to impress my Minecraft-obsessed friends. Enjoy, and expect to see more Minecraft-in-real-life instructables from me soon.
