Dagen H Traffic Gloves

​Origin
Dagen H (H day), today mostly called "Högertrafikomläggningen" ("The right-hand traffic diversion"), was the day, 3 September 1967, on which traffic in Sweden switched from driving on the left-hand side of the road to the right. The "H" stands for "Högertrafik", the Swedish word for "right traffic". This decision was made to reduce the number of accidents, and for a while worked before accident levels returned to their normally somewhat high number. Before the actual change, the logo for the campaign was advertised on many commemorative items including milk cartons and underwear, and there was even a contest for entries of songs about the change. Additionally, many tram cars were abandoned after the switch due to being unable to move.

​This pair of colored gloves was used in 1967 by Swedish authorities in order to remind drivers they should drive on the right as the traffic was changed.

​Effects
​When one glove is pointed at something or someone, the movement of whatever the target was becomes inverted (i.e. a person running forward would uncontrollably run backwards instead). This inversion can only be itself inverted by the other glove. If both gloves are pointed at something at once, the inversion can become more intense, from ceasing movement when the intent is to move and vice versa, to reversing bodily functions such as digestion or blood flow. If amplified somehow, it is theorized that the gloves could potentially reverse the rotation of a planet.
