Valentine's Day may mean chocolates and flowers for most, but for Valve - and fans of its spatial puzzler Portal - it means falling through orange and blue holes and tender moments with maniacal AI overlords.
In honour of Portal 2, the developer has released this range of Valentine's Day cards for you to customise, print off and maybe - just maybe - actually mail to your sweetheart. Or you could edit the pdfs or jpg files and just email it to them, subject line "thinkin of u".
The cards are thoughtfully available in not just but also English, French, German, Japanese, Swedish and Portuguese.
Portal 2 will be out on the PC, Mac, Xbox 360 and PS3 in April 2011.
