Looking for the perfect holiday gift for that Portal fan on your list? Then ThinkGeek went and did you a solid by concocting an officially licensed talking portrait of Portal 2's put-upon, cranky-pants, Aperture Science founder Cave Johnson for public consumption. The purveyor of combustible lemons (in concept) has the ability to hang on your wall and spout 13 different, motion-triggered, JK Simmons-voiced phrases — all in a real wooden frame (ie. not that Ikea stuff). It's currently being sold for $39.99.

The rub? It's quickly sold out. The non-rub? ThinkGeek estimates that they'll be restocked just in time for last-minute holiday shoppers willing to pay for overnight shipping (the website has a date of 12/17 as when they'll have more in stock for sale). You can check out more images of the portrait, as well as discover all the phrases the item can spout on ThinkGeek's product page here.
