In medusa II I continue an experimentation I began with the installation medusa. In medusa II, the new iteration of the installation, which is based on the same chaotic principle, the aquarium contains a similar setup; the pumps and the cloth are still present. The relays, TL lights and strobes however, have been removed. Instead, a metal beam with a motorised cart is placed above and in the length of the aquarium. The cart has a red cross-laser attached to it, which points towards the bottom of the aquarium. Here, sensors are placed to detect the laser and more importantly, to detect when the laser is obstructed by the cloth. The sensors lead to a microcontroller (arduino) which controls the motorised cart. The programme on the arduino ‘scans’ for the cloth and if it detects it, the cart will slow down. When it ‘loses’ the cloth it will scan again, and so forth. The movement of the cart is thus based on the chaotic movement of the cloth.
