The Caterpillar is an extension cable intended to engage its owner into a dialogue about wasting energy with devices in stand-by. The Caterpillar has three different modes: It breathes slowly in the case of „normal“ energy consumption by a device, such as a TV. If the TV is switched to stand-by, the Caterpillar starts to twist and turn awkwardly, as if in pain. This can be resolved by disconnecting the TV entirely. The Caterpillar touches upon people‘s tendency to help and take care of living things. Through its behaviour, the Caterpillar conveys an attitude towards the consumption of electricity –, the „pain“ implied by stand-by – and offers a simply remedy, framed as an act of helping.
