Whoever made that awesome Portal Christmas tree should get these officially licensed Companion Cube string lights. Hopefully they won’t short and burn your house down. Because I’m sure they remember what you did.
The 10′ cord comes with 10 Companion Cube lights. You can buy multiple strings to make a longer chain of loving inanimate objects.
You can order the Portal Companion Cube String Lights from ThinkGeek for $25 (USD). Tiny test subjects may or may not be included.
