Alexandre made his own door opener – “I sit about 5m from my office’s door. So, every time someone ringed the bell I had to stand up and open the door. That would be fine if the door did not have an electric door opener just next to it! An ingenious device that allows you to open the door by simply pressing a button. Because of this, the device had no use at all. After all, if you were in front of the door, you could simply open it using the handle. Thus my goal was to give a purpose for the simple life of this poor electric door opener (and, of course, to save a walk of 5m ten times per day).” [via] Link.
