Automatic door

how or where is this useful?

lol this isn't creative or original at all...I wish the Japs would actually focus on useful stuff instead of crap

well they could make this solar powered i mean its a door sun should hit it it could be a solution to using resources like wood etc but not really neccesary cool though

...such as?

Hello. The future of our goddamn planet? If we keep blowing resources out of our anuses in pursuit of retarded crap like this, we'll be underwater, boiling, or frozen within a century.

This is the worst idea ever. Beside all the flagrant glitches where door does not partially slide and can cause unintentional injuries, the implementation is flawed from the base. For instance, it does not take into the consideration that the upper most pieces do not scan a beam diagonally downward to take one's height into consideration. This blows. Damn useless inventions.

why?
just use regular door. it is cheaper, way cheaper.

Living up to the name. Nice job.

How dare you suggest I picked a name that suits my personality when signing up for this site!!!

That would be cool technology for stairs.. like they slide out as you walk up them. It would just suck if it didn't work sometimes..
