[[SADLY valve apparently has a problem with this design to gets it removed on any site I upload it on, so it currently is not available, sorry guys..]]
One thing I have searched extensively for on the web is a Portal/Aperture science Calendar, but I couldn't find one (unless you can prove me wrong?), so, I made my own :], and now it's available to everyone.
12 months (plus you can choose what month to start on! not just January now), 12 fully original designs made in the familiar style from the games warning signs in every test chamber, all illustrated to help instruct new handheld portal device users everything from couch fishing to how not to turn into a pile of ash, a must have for any Portal fan, with xmas so close it's a great gift too, get it in time for wrapping
