Here's an example of how you can paint it to look like the one from the game.
This is my attempt to recreate the Weighted Companion Cube from the game Portal, into a small, somewhat useful box. I dunno what you can put into a box that's only 2" in size, but I'm certain you'll think of something.
PLEASE NOTE: This item comes unpainted, white, and a little gritty. Use Acrylic paint to do the coloring. It absorbs well and gives the box a much smoother feel with 1 or 2 coats.
If you want the box to light up, just put an LED Tea-Light inside. Use a light that is cool to the touch, as the cube might melt or burn if it's hot. Paint the white areas with a thin coat of paint, and add an extra coat to the gray areas. If you add a little hole for the wiring, you could use this as a groovy nightlight.
The Material is Nylon, called "White Strong & Flexible" rather durable. Just the same, it's not a toy and shouldn't be left with children or pets.
