The Square Root of Negative Three
- Originální název: The Square Root of Negative Three
- Režie: François Miron
An ad for the famous Ka-bala Ouija board by Transogram (1966), the first game to glow in the dark, opens a powerful barrage of optical effects in which Lysol disinfectant, the silence of stones and the hope of angry children intermingle with scientific ravings.
