How to put it together
- 1
Find a cardboard box that fits your torso comfortably and cut holes for your head and arms.
- 2
Spray paint the entire exterior of the box with gray or silver paint and let it dry completely.
- 3
Print or draw a computer screen design (such as a retro desktop, a loading screen, or a blue error screen) on poster board and glue it to the front of the box.
- 4
Securely glue or tape the lightweight keyboard to the lower front edge of the box, protruding slightly like a tray.
- 5
Attach the computer mouse cord to the side of the box, letting the mouse hang down or gluing it next to the keyboard.
- 6
Put on your neutral base clothing (black shirt and pants).
- 7
Carefully slip the cardboard computer box over your head and adjust for a comfortable fit.
Makeup & hair
Keep hair neat and simple. You can optionally wear a headband with a green 'power button' symbol or a USB symbol drawn on it.
Computer for couples, groups, kids & more
- couples
- One person goes as a computer, and the other goes as a computer mouse, a Wi-Fi router, or a '404 Error: Costume Not Found' t-shirt.
- group
- A group can dress as different classic desktop windows, error messages, or different components of a PC setup (monitor, keyboard, mouse, tower).
- kids
- Use a smaller box to create a wearable laptop where the screen folds up in front of their chest and the keyboard rests on their waist.
- Plus size
- Choose a larger appliance box (like a microwave or washing machine box) and cut generous arm and neck holes for a comfortable, breezy fit.
- pet
- A small cardboard 'monitor' shell that fits over a pet harness, displaying a cute 'loading...' screen.
Tips
- Make sure the armholes are cut large enough so you can easily reach for drinks or snacks at a party.
- Keep the cardboard lightweight so it doesn't strain your shoulders after hours of wear.
- If you plan on sitting down, design the box to end at your waist, or make the keyboard detachable via hook-and-loop tape.
- Add battery-operated LED fairy lights around the screen border to make the 'monitor' glow in dark rooms.

Did you know? The first electronic digital computer, the ENIAC, built in 1945, weighed over 27 tons and took up an entire 1,800-square-foot room—making it much harder to wear as a costume than today's versions!
