Elevator buttons

One thing about being in an elevator with other people is that usually people stop talking once they are in, it is crazy... imagine 8 people not talking to each others for a few minutes with a background music of Mozart, my friends know me, we are like peas in a pot and whenever we are together in the elevator with strangers it makes me giggling, don't ask me why but I don't know the reason. Therefore I found something really cool on internet: Educational elevator buttons, really love this. I wish to have something like it, ahahha what would happen if you work in a building of 70 floors :)
