The box features a switch and a hinged lid. When someone presses the switch an arm inside lifts the lid, switches the switch back in the opposite direction and then closes again. Useless, but strangely compelling.
After seeing the original most useless machine ever I couldn’t resist making one myself, not for myself though, this one was a present. As the site hosting the original is horrible, I used the nice clear instructions provided by Make Projects.
I spent some time looking for a suitable box to house the machine’s useless innards, but finding one the right sort of size without any ugly decoration proved tricky, so I opted to make the box myself.
