I want to go to Japan for a bunch of reasons but mainly because of how advanced they are technologically.  Have you ever even heard of a semacode?  Essentially it’s a visual barcode.  You take a picture of the Semacode with your cameraphone and the phone processes the image and it gives you the URL for something.  For example the image on the left is a semacode for the wikipedia entry on Semacodes.  (so meta)  The image on the right is the Semacode for The Last Minute.

Semacodes allow you to do really cool/nerdy things like hit up a videobooth in Japan and have the videos beamed to your video cell phone automagically.  As seen in this video.  I don’t quite understand the pink fluffy fashion accesories in this video…  [via]
