is a huge insect-like structure that moves independently and gracefully with the wind.
Theo Jansen has been developing his beach based environmentally friendly kinetic sculptures for about 20 years. His first biomorphic machines walked only in one direction. Since then he has developed his Strandbeest's as he affectionately calls them, to walk, powered by the wind.
Essentially, Strandbeest's are made from recycled materials - cable, PVC conduit and plastic bottles. Animaris Siamesis, his most recent incarnation is driven pneumatically - wind-powered pistons compress air into bottles, from which it's released to drive the walking legs.
Amazingly his latest version stores some of the wind's energy in plastic bottle 'stomachs' to be used when there is no wind, as we see in his video, here, his graceful creature doing a short walk on compressed wind from the wind stomach.
He intends these graceful creatures to continue to walk up and down the beach long after his life has passed, as we hear in this other video.
