Holiday Greetings from Aperture Laboratory

Valve have created Portal themed Christmas Cards. Available from The Valve Store for $14.95, you get 15 cards featuring 5 different humourous greetings. It's a shame that it probably won't arrive in the UK in time for Christmas but if you're in the US, it's only 2-3 days delivery which is perfect. If you've never played Portal, you won't understand the greetings so go and play Portal now!

Anyway, here are the greetings and a picture of the card (might contain spoilers).

"If the Weighted Companion Cube could speak - and the Enrichment Center reminds you that it cannot - it would wish you and yours... All the Best this Holiday Season!"

"The Enrichment Center reminds you to Have a Happy Holiday until you are instructed by a superior to discontinue having a Happy Holiday."

"Hoping you and yours willingly assume the Holiday Escort Submission Position this Holiday Season!"

"The Enrichment Center reminds you that any appearance of danger is merely a device to enhance your Holiday Experience"

"Remember when the platform was sliding into the fire pit, and I said, 'goodbye' and you were like 'No Way!' and then I was all 'we pretended we were going to murder you' and then I sent you this Holiday Greeting card? That was great."
