Yesterday I came up with this idea: printing all the levels of Super Mario Bros (1) and hanging them around your room in the correct order. Awesome, I wonder if anyone has done that before.
I guess printing some iconinc game picture with Rasterbator would be nice too.
Oh and then there are these paper figures you can print/cut/fold/glue yourself. I've always wanted to do 1 of those, but I never took the time. Maybe I'll do the King of Red Lions or whatever The Wind Waker's boat was called.
I have a Majora's Mask clock. It was originally a MM sticker and a random clock. Picture: http://www.gametavern.net/forums/attachment.php?attachmentid=3363&d=1344770321
Speaking of which; printing the (best of the) Majora's Mask masks and hanging them on the wall would be pretty sweet.
